Trigger Warning/ Triggering

Y'all, Lu Feng needs to get popped in his mouth. Holy hell. I can not STAND him. 😭 He's a little psychotic demon. Atrocious. Why is he so damn aggressive??

Oh and Cheng Yi Chen? He is SOOO aggressively spineless and is too comfortable being a doormat. Really wish he'd find his brain and get some standards.
The more Cheng Yi Chen 'tolerated' from Lu Feng, the angrier I got. Show had me so livid. How is he going to look like absolute crap and take a bully for the person responsible for the terrible state he's in.
"Why do you always want to leave me?" My guy, do somw self-reflecting. My word

Lu Feng treated his mom and brother like shit. What does Yi Chen do? He betrays them for said that man. Just to keep being treated like trash! Like hello, are you good?
They all need to learn how to stand tf up and walk away from toxic relationships.

I love the actors but the show is... idk. Please recast them in a better show, I beg ?

1.) This series started off SOOO good. I caught myself smiling as if I was in the series when I watched the first episode, but it went downhill and I don't know how to feel. I kept hating Lu Feng, then he'd do something sweet and I'd like him then remember what all he did. I'm soo happy Lu Feng got help in the end, they deserve to have a happy ending but I just wish some things in this show didn't happen :/ I had to skip over a couple scenes cuz it was too uncomfortable to watch.

2.) Fuck Xiao Chen's and Lu Feng's Parents tho I can truly never understand why parents decide to treat their kids like underwear with a wet skid mark just because they like the same gender, glad they died fuck them.

3.) I want to add it was very clear Lu Feng had issues from the 2nd ep, I was really hoping he'd get help from ep. 2 to the end and I'm seriously glad he did. Xiao Chen was also clearly blinded by love as if I was in his shoes I would've left the second he tried to guilt trip me in to having sex.

Anyway actors were amazing and I would love to see them in a show with a sweeter plot! Please and Thank Yewww

why r yall constantly defending lu feng when he’s a textbook narcissist

If I read one more comment about how the little brother is annoying and how he’s destroyed his brothers relationship I’m gonna lose it. I’d like to gently remind everyone that lu feng as opposed to yu chen is older and *should* be emotionally and mentally more mature but instead chooses to act like a 4 year old whenever a conflict occurs. Not only is he lacking any empathy or critical thinking skills but also he likes do mistreat and deliberately hurt the person he claims to love. It’s come to a point where his behaviour is so utterly pathetic that I dislike his character even more then all of the homophobic parents together. And let me tell you I’ve watched a few dramas and I have never felt that way before. I’ve never even written a review before but my hate for this fictional man has reached a point where I’m gonna implode if I don’t write it down. That being said I don’t condemn people that enjoy the drama, like or defend lu feng (or only just a little bit). I understand that red and black flag characters can be fun to watch. BUT I need the people to lose the „I can fix him“ or the „He’s just misunderstood“ mentality regarding really problematic, toxic men. Not only because of the whole misogyny and patriarchy thingy but also just because I find it really annoying. Thank you and good night.

Ok, this is trigerring, very triggering and gets really dark....but damn good despite all that!!!!

Be prepared to be very angry, livid, in fact, fuming and cursing a lot.....but don't you dare miss this!! Great story, acting, script...and wait till episode 5-6, when things get really good. I mean bad...really BAD and gets you hooked!!

As the story progressed, with each episode this just gets better and better....but if you have been through homophobia, family opposition and blatant arm-twisting by parents and family, be warned that this will trigger you...BIG TIME.....the bottom line is -these parents, they needed to have died much earlier....BEFORE they ruined everyone's life...and queer people need to find their spine and STOP ruining their own and other people's lives just so that they can be the 'good child' to their monstrous parents, and play the victim of being the martyr. Ok, rant done, this is good...damn good...don't miss it

BL-needle Score: 6. It has a lot of men loving men, but not really BL-ishq, if you know what I mean

Started out uber cute, the ML looking super handsome, doting on the MC, and bordering on obsessive-possessive.. the super red-flag-ey, won't listen to no -kind ...just when they find each other, their love story quickly veers towards a complete mess and heartbreak, with families, money, reputation and homophobia ruining everything....separating them, across oceans, and timelines...and just when you think the bish parents, and entitled, opportunistic, younger bro can't be any worse...SURPRISE....the protagonist himself sabotages everything by walking away, getting married and completely blindsiding the one person who loved him against everything, and through everything.

At Episode 8 right now when things have just started to turn good, the wronged lover is finally seeming to have his time...though I get a feeling that Lu Feng will eventually melt and succumb to this undying love for Cheng Yi...I wish he takes till the very last moment to do so though...because if I was Lu Feng, I would rub it in harder...much harder

Ep 9 DAMN!!! This has gone absolutely pitch dark now.....beyond toxic....the devil in Lu Feng is unleashed...all that anger, jealousy, repression, sense of betrayal, has made him into another person altogether :(

There was a movie on the same book in 2016, which has rave reviews. While I haven't watched that one, I am definitely glued on with this show. As I already said, Damn Good!!

What are you waiting for...Go Watch!!

Rape can't be excused

Sorry not sorry, but I'm sick and tired of bls that allow rapists to have a happy ending. Having that in the big 2026 is embarrassing. No matter how good the acting or cinematography is, they allowed his actions to be excused because he is sick in the head. And I can already hear people say that's it's just fiction. But life imitates art. Seeing the way people excused the rape by saying the victim deserved it since he didn't fight hard enough for their love is evidence enough that films have consequences on the perception of reality that people have.

A Love Story that forgot to show the Love

I honestly didn’t find this to be a love story so much as a character study of Lu Feng’s deteriorating mental health. I felt absolutely no romance from any of the couples because we never actually got the journey of them falling in love—they were already sooooo in love and I was just left thinking, “why?”

The first thing that gave me serious ick was the main CP’s first time in ep 2 😣 Yichen was clearly scared and needed comfort, but Lu Feng took the whole thing in jest and forced himself on him (while crazy romantic music played, ugh). Even afterwards, when Yichen was shown to be distraught, Lu Feng made it all about himself, and since then I genuinely couldn’t understand why Yichen even remotely likes him.

So the show felt more like a case study of someone mentally unwell who harmed not only himself but everyone around him. The bipolar reveal also wasn’t handled well because it almost makes it seem like all bipolar people are like this, which isnt true :( I do appreciate that they at least acknowledged that something is wrong with him and that it needs attention.

The one time I felt emotional was in the last episode, when Lu Feng listens to the iPod and is reminded of who he used to be. That whole idea of coming home to yourself was actually kinda moving.

Other than that, the characters lacked depth and their reasoning was never really explored, which made it hard to connect with them. The actors did well with what they were given, but nothing much to write home about.

I’m all for red flags, but the forced scenes throughout the show and the way they were framed honestly just made me kinda queasy.

For a VERY specific audience, do not expect logic or maturity

The experience of watching this while it was on-going is genuinely one in a million. I could not keep up with the discussions of characters being irredeemable one week and then being redeemed the next, somehow. This show had a LOT of flaws, but goddamn does it keep you hooked.

The first few episodes are filmed in such a close camera lens and shots that it genuinely feels a bit obsessive and personal, later on you understand why. The characters were mostly one dimensional, but Lu Feng, what a character. Watching the show just to see what he does next became the new motivation for me honestly. The acting was amazing from him and he did NOT hold back.

Xiao Chen...I wish he was braver.

Anyways GREAT ost ! Overall good watch.

Is the hype justified? Kinda...

I like dark (and at times toxic) romance but I do have some things that will immediately turn me off a story. Now, where I draw the line is pretty subjective, I enjoyed "To My Shore", which arguably crosses similar if not worse moral lines.

I suppose it's because in "Double Helix" it seems like Yi Chen had no possible power in or outside of their relationship. (Although Lu Feng's devotion could imply that in their dynamic, Yi Chen had the upper hand, this is not the case.)

Yi Chen is punished for doing just about anything Lu Feng doesn't agree with. And Lu Feng's treatment of him was domineering and abusive. Using his superior resources, physical strength and ruthlessness to manipulate and psychologically torture Yi Cheng and hold him captive.

And yet Yi Cheng gives him countless chances despite Lu Feng doing nothing to atone for them until going to therapy and ultimately in-patient care (which he is basically forced into by way of ultimatum.) His actual improvement shown with a montage in the very last episode. And I also don't feel great about justifying his behaviour somewhat with "mental illness".

I worry about the people I see defending Lu Feng online. You're more than allowed to like the character/enjoy a toxic ship but to justify his entirely selfish and abusive behaviour is concerning.

I gave the show 6 stars despite loathing the storyline because I really liked the second couple (Yi Chen's brother did nothing wrong besides his initial homophobia, he was right to protect his brother imo). The show's production quality was quite satisfactory and I honestly enjoyed the performance from Lv Si Tong and Ayden Sng.

I look forward to their next project because I do think they're talented and have great chemistry. This show just really went downhill for me story/character wise.

a mix of cuteness, toxicity and a lot of emotions

first id like to talk about the cast, they did such a great job esp ayden's performance its so great, a great actor indeed, he portrayed lu feng so well,and Lu Si Tong is such a cutie he is so adorable
the ost is great, an intriguing story which switch from cute to toxic and dark to cute again and give us all type of feelings from giddiness, to sadness, to frustration and anger, to more giddiness from cute scenes
i highly recommend it for people who can handle toxic and dark stories, its better to check the tags and the trailer before watching tho as it can be very triggering

love story worth fighting for but a script too lazy to let its characters fight for it

Double Helix opens with something genuinely beautiful. The first two episodes portray Lu Feng and Cheng Yi Chen's student life with real tenderness: two people drawn together despite everything around them telling them not to be. Underneath that romance sits a story with real weight: a world that refuses to accept their love as love. Cheng Yi Chen's own mother treats his sexuality like a disease to be cured rather than a truth to be accepted. That is the show's real subject. It is the story Double Helix should have told.
It is not the story Double Helix tells.
Instead of staying with that slow, devastating pressure, showing how rejection from family, society, and institutions can quietly erode two people from the inside, the writers reach for something far blunter. To manufacture the conflict that drives Lu Feng and Cheng Yi Chen apart, the show turns to sexual violence. The choice is jarring against everything established before it: this is a Lu Feng who fought his family, defied social expectation, and gave up his inheritance to be with Cheng Yi Chen. Nothing in that build-up earns the abruptness of what comes next. The show needed the audience to turn on him, and rather than letting that turn arrive through accumulated strain, it manufactured it in a single act.
The same shortcut resurfaces later, in a different shape. Having used violence to break the relationship apart, the writers reach for a psychiatric disorder to explain it after the fact. A diagnosis is not accountability. It re-labels what happened rather than sitting with it, and it lets the show move toward its happy ending without doing the harder work of making Lu Feng actually reckon with what he did.
What makes this doubly frustrating is what the writers had already built and chose to abandon. Cheng Yi Chen is established early as someone capable of real loyalty, caring deeply for the people around him. But that loyalty stops at Lu Feng. When the relationship becomes difficult, he does not fight for it. He walks away with striking ease, and years later, rather than confronting his mother's rejection of who he loves, he marries a woman he has no feelings for simply to keep the peace. It is the same avoidance the show itself is guilty of when things get hard, take the easier path rather than do the difficult work of confrontation. Cheng Yi Chen never matches what Lu Feng sacrificed, and the imbalance is never acknowledged, let alone explored.
Double Helix had a story worth telling about love that society refuses to recognise it, about the quiet cruelty of a mother who sees her son's identity as something to be fixed. Somewhere in its first two episodes, the show knew this. But underneath every choice that follows is the sense that the writer had already decided who each character would be before the story ever earned it. Cheng Yi Chen was cast as the victim, Lu Feng cast as the red flag, both fitted into roles rather than allowed to become them. It chose spectacle over meaning, shock over substance, and predetermined character labels over honest storytelling.

Trigger Warning for SA, Kidnapping, Confinement, Isolation, & Abuse

I was really looking forward to this one. Just a warning; my thoughts are all over the place right now so this review may not be the most organized. It's also almost 3am hehe so there may be some spelling and grammar mistakes.

This is a series where there aren't many characters that aren't going to frustrate or annoy you at least once. The MC's work friends probably won't, and maybe Yi Chen's (the little brother) boyfriend won't, but he also didn't have much personality outside liking little Yi Chen. Ke Lu was fine too, but we didn't see him much either. Lu Feng's sister is pretty cool as well after their father dies, you can tell she cares about her brother at least.

Can I just point out how stupid it was to have the MC & his little brother share the same name.

Don't get me wrong it wasn't bad, but it did feel like it was trying to hard to be something it wasn't. There was always something happening that would remind me of To My Shore & Revenged Love; mostly in the dialogue.

The OST was alright. I didn't hate it at least, there was just too much of it. Once or twice an episode would be fine, but it happened sometimes 4 or 5 times where we would get a flashback/montage with a lyric song overlaid. The flashback/montage's were over done as well. We didn't need that many.

We didn't need so many NC scene's of the second couple either. I would have much rather have seen how the little brother fell in love. I don't believe it was love at first sight like with Qin Lang and Lu Feng. We don't get enough of the second couple.

The fashion was probably my favorite thing about the series. I liked the Yi Chen siblings clothes, especially Xiao Chen, but I also really liked Zhu Sha's. Not many people can pull off a bubble skirt (at least not many I've seen).

I liked that we got to see our main couples relationship at basically every stage. High school, college, right after college, and then meeting again after 5 years of separation.

The acting was good. Xiao Chen seemed overly dazed at times, but I chalked that up to his character being overwhelmed with the situation. I especially liked that you could tell something was wrong with Lu Feng just from his eyes.

The last thing that I feel is worth mentioning on the positive side them giving a reason behind Lu Feng's aggression and impulsive behavior. Bipolar disorder isn't something I know much about so I can't speck for accuracy, but this is the first time I've seen them give, or at least acknowledged, a mental health reason for the ML acting crazy obsessive over the main character. Xiao Chen being a trigger for him also makes perfect sense if his love for him run's so deep, and they are constantly being torn apart. I also like that we got to see him working though it. Was this accurate treatment? I have no idea. It felt like it would hurt more than help, but my medical training didn't cover this type of mental disorder.

Would it be horrible of me to say that I was happy that the parent's all started dropping like flies? I didn't care about any of them and I don't think we were meant to. Lu Feng's father died & Lu Feng's tears felt like those of relief. I'd cry in relief too if my abuser died. The Chen's father? It happened with no fanfare. I'm not even sure they told us why or how he died. The most memorable thing he did was fly into a rage and lock Xiao Chen in his room. The Chen's mother? Lady was really holding on for that wedding wasn't she? She wasn't going to be able to rest till she saw her son in a loveless marriage that anyone with eye's could see would go no where.

(I've heard in the book they actually have a kid and so does Lu Feng from a one-night stand & I'm interested to know how that affect's the whole kidnapping thing. I may have to read the book.)

BACK TO THE MOTHER. This women pissed me off. I already didn't like her for not even worrying about her son who had just been attacked, but was more worried about him not being "normal" as she put it. Then she kept trying to set him up with girls & ignoring what his type really was. At the hospital though was were I really wanted her to just bite it. When she was giving this long death bed guilt trip to Xiao Chen about how at least one of her sons needed to be normal or it was a waste of time raising them, how he corrupted his little brother, how she had saved up so much money for him to start a family with. It's like being normal is more important than her children's happiness. If only she knew that Xiao Chen was picturing himself marrying Lu Feng while marrying Zhou Lan.

The wedding was a shotgun wedding.

Since I brought her up~ I don't like Zhou Lan. Not because she married Xiao Chen, in that she was just being a good friend while also getting to marry her crush. Can't blame the girl for taking the opportunity that landed in her lap. I didn't like her at the beginning because her character felt desperate, but it was near the end where she brings a gun and accidently shots Xiao Chen that really solidified my dislike. Why didn't she call the cops? Why would you enter someone's home with a gun? She didn't even know anything about Xiao Chen & Lu Feng's relationship, didn't know anything about the situation, or weather Lu Feng has a gun, she didn't take into account that Xiao Chen could have been hit. She simply didn't think at all. If you think someone is being held captive, confirm and then call the cops. Don't take the law into your own hands. I pisses me off that she didn't get any punishment for this either, or if she did we aren't told about it. I don't care if her reasons were good it's still attempt of murder.

Episode 9 was were Lu Feng went from a toxic red flag to a psychopath. Props to the actors during this episode because it was a lot, especially the biting which was real at least once. Sadly we only got this level of toxic psycho behavior for only one episode. I know I'm a horrible person for wanting more. I just felt like they tried to pack it all into one episode when it could have been spread out into two episodes and had more impact.

Finally the thing I HATED most. Who thought that 3D model of the city was good? It was so fake & ugly it hurt to look at. I'd be embarrassed for people to see my name attached to it. I don't know what the budget was but it must have been scaping the bottom of the barrel. I'm going to assume they didn't have the funds for a drone, or maybe legally they can't do drone shots. But a picture from Google images would have looked better. The worse thing is we didn't need these city or sky shots at all! When we have a time skip sure use it, but they subject us too these moving 3D model's multiple times each episode for no good reason. Just don't show us anything at all. Transition from one scene to the next using the fade to black method or something.

Was that a bit harsh? Probably, but it bothered me throughout the whole series and I couldn't not say something about it.

While I was disappointed by many aspects of the show I'm still glad that I watched it.

A Powerful Yet Painful Story of Love and Mental Health

Double Helix was a fascinating and emotionally intense series that follows the relationship between Cheng Yi Chen and Lu Feng. What begins as a rocky friendship gradually blossoms into a heartfelt romance, and the early development of their relationship is one of the show’s strongest aspects. Watching them slowly lower their defenses, learn to trust one another, and genuinely care for each other felt natural and well-written, making it easy to become invested in their journey.

Once they finally become a couple, their happiness is short-lived. A photo of them spreads throughout the school, igniting conflict both at school and within their families. I especially appreciated how Lu Feng remained unwavering in his love for Cheng Yi, refusing to let public opinion or societal judgment dictate how he felt. His determination to stand by Cheng Yi, despite the backlash, was one of the most admirable aspects of his character.

Unfortunately, the two are forcibly separated, and years later they finally reunite. Just as it seems they might finally get the future they always dreamed of, new obstacles arise. Overwhelmed by pressure from his mother and brother, Cheng Yi makes the heartbreaking decision to end their relationship. Feeling as though he had always come last to everyone else in Cheng Yi’s life, Lu Feng reaches his breaking point. His unresolved trauma and overwhelming fear of abandonment gradually consume him, leading him down a path of increasingly obsessive and abusive behavior.

The series does an excellent job portraying Lu Feng’s deteriorating mental state. Rather than treating his actions as simple villainy, it explores the emotional wounds and psychological struggles that shaped him. While his behavior is never excused, the progression of his mental health and the reasons behind his actions are presented with care, making him a tragic and deeply flawed character rather than a one-dimensional antagonist.

As painful as the middle portion of the story becomes, it ultimately serves a purpose. Once the truth finally comes to light, both characters are forced to confront their trauma and the damage it has caused. After enduring a few more hardships, Lu Feng finally opens up to Cheng Yi completely, allowing Cheng Yi to provide the support, reassurance, and encouragement he desperately needed.

One aspect of the series that irritated me was how poorly both Cheng Yi’s and Lu Feng’s parents handled every situation. Rather than protecting or supporting their children, they became the source of their emotional pain. Their inability to understand, communicate, or prioritize their children’s well-being played a significant role in the trauma both young men carried into adulthood, making them some of the most frustrating characters in the series.

In the end, Cheng Yi Chen and Lu Feng finally achieve what they had always longed for: the chance to truly be together. Cheng Yi finally chooses their relationship and decides to put them first, while Lu Feng is finally able to experience the unconditional love and acceptance he had been searching for. With that love comes healing, allowing him to begin letting go of his lifelong fear of being abandoned again.

While the show does contains many toxic and uncomfortable moments, particularly throughout the middle/ending of the series, it also emphasizes accountability, healing, and the importance of seeking help. This certainly isn’t a romance that will appeal to everyone, but for viewers willing to engage with its darker themes, it offers a powerful look at trauma, mental illness, codependency, and the long road toward recovery.

Overall, I really enjoyed the series. The cinematography was beautiful, with crisp visuals and thoughtful framing that enhanced many of the emotional moments. The soundtrack was equally impressive, perfectly complementing the story’s emotional highs and devastating lows. Although its subject matter can be difficult to watch at times, Double Helix ultimately delivers a compelling and emotionally resonant story about love, trauma, healing, and choosing one another despite the odds.
