All of that work (hardcore spoiler)
All of that work only to rush the last episode like that. Absolutely no explanation as to why and how they concluded that his original father was his biological father. The entire series was centered around him finding five potential sperm donors to be his biological father and they pulled a stunt like that? Five minutes of a scene that landed us back to his original biological father? And with no elaboration. I am so confused.Was this review helpful to you?

The end. It was really wonderful and I think I will carry this drama with me for a very long time.

Such a emotional masterpiece!!
Mr.Plankton changed my life.The bad taste still on my lips because life can be full of crap and hae jo of all people deserved to live, to have everything that life has stolen from him.
This drama is so well written, the characters emotions, fears and joys, everything so raw and truthful, wich make you fell right there between the story. I'm so sad that I didn't watched it before, especially because I was afraid of suffering with grief of a person who doesn't even existe but...
I could never forget you 🍀🪼.

A Beautifully Acted Drama but Deeply Toxic Romance
There’s been a lot of praise for Mr. Plankton, but I have to disagree. While the male lead Woo Do Hwan, is undeniably attractive, his character is absolutely toxic. He breaks up with the female lead without a clear reason, only to storm back into her life on her wedding day—kidnapping her against her will. Meanwhile, the groom Oh Jung Se, though portrayed as dim-witted, genuinely loves her and has a kind heart, yet she treats him with outright rudeness.The male lead also struggles with a terminal illness and embarks on a desperate quest to find his biological father, taking DNA tests with possible sperm donors. Instead of dealing with his issues alone, he forces his ex-girlfriend—whom he kidnapped—into accompanying him. While the drama delivers some romantic moments and explores the pain of not knowing one's origins, it leans heavily into toxic behavior.
On top of that, the female lead is dealing with early menopause, which she hides from her groom. Instead of being honest, she lies about being pregnant just to go through with the wedding, making the situation even more bizarre. The drama is filled with deceit, betrayal, and a complete lack of open communication, making it hard to relate to in today’s world.
That said, the acting is fantastic, and the characters are well-written and portrayed beautifully. However, if you're looking for a happy ending, please skip this one—it has a tragic ending.

Great storyline with fenomenal acting of Do Hwan that makes you laugh & cry.
I was hooked from the first episode, as the drama keeps you entertained all the time. There is no boring moment or bad scene or useless character. The drama has great screenwriting, and the director has done a superb job. The drama will make you laugh and will make you cry.I have to say Do Hwan was perfect for this role; he slayed! I am really impressed with his performance, and their chemistry is amazing. They took us on an amazing journey, even though we knew it would not be a happy ending. I loved the dynamic of the drama and all the characters.
Even though you will cry your eyes out in the last episode, it's worth it. Do Hwan's acting was phenomenal. It will stay with me for a long time.

A sobering lesson on karma and healing
Mr. Plankton died at the end. BUT it is the best end he COULD have had, since his karma was so bad and he never overcame it,so at the very end of his life, when he was forced to, he tried to clean up his life trauma. HE TRIED TO THE BEST OF HIS ABILITY
he was a very immature and wounded person so his "best" was still quite disfunctional.... He refused to listen.... Looking good and strong on the outside, on the inside, he was ... broken ... and not working hard enough to put himself back. He did not love himself enough to really really really really really TRY.
This movie is horrifying, sad, and very sobering REALITY CHECK because it shows you to your face what happens when you refuse to clean up your past.
Mr Plankton did not try hard enough to change, and there were consequences.
Mr Plankton was not ready to take in good life. He took a crumb, bc that's all he could handle, and then died from his inability to hang onto his happiness
HE WENT AS FAR AS HE COULD HAVE. So yeah he died in peace.
HE NEVER DID THE INNER WORK TO TEACH HIMSELF THAT HE CAN LOVE HIMSELF AND BE HAPPY AND THUS MAKE HIS HAPPINESS POSSIBLE AND **** LIVE ***** like that
The side character of FL's boyfriend is fun and interesting during the drama, but ... after all this time, i remember only Mr Plankton. Bc he was so genuinely SAD, deeply sad inside him.... Sad, unloved, shaken, scared, abandoned, alone..... although he wasnt really. He found ppl to love him and acted nice to some but he himself wasn't opening to loving himself... . and thus was quite cruel to others, unintentionally
Very sad, tragic story of what happens when you dont clean up your shi%

Emotional journey
This show wasn’t just entertainment; it was an emotional journey. With incredible actors, a compelling story, and breathtaking scenery, it truly had it all. Most importantly, it had heart. Every character was perfectly crafted, making their struggles and growth feel deeply personal. Even though the ending was bittersweet, by the time it concluded, you felt emotionally exhausted—but in the best way. It’s a beautiful exhaustion, a testament to the power and depth of the show. Highly recommend.Was this review helpful to you?

Still bawling… Mr. Plankton hit harder than I expected.
Damn, I’m still bawling my eyes out. I didn’t expect to cry this much. I’ve seen a lot of endings like this lately, but this one really broke me—maybe I’m getting soft. His acting was absolutely on point. And the female lead… the way she smiled at the end, despite going through the pain of losing him, hit me so hard.This wasn’t just about romantic love—it felt like something deeper. I loved how the plot showed them tangled together, despite their completely different mindsets and ways of living. The female lead was there purely for love—just for love. Even though she hated his outlook on life, she still chose him. She just wanted him.
God, I’m still bawling…

Mr Plankton or how to turn an awfully sad fate into a fun story.
At first you get some "uncontrollably fond" vibes but you quickly understand that it is totally different. This drama is like its main character, it does whatever it wants, it's never really serious and it literrally ends with him. You can like or dislike the end but it actually stays true to itself.You keep smilling even in teary moments,. Sometimes, you feel the sadness and the heartbreak but end up laughting...
You can like or dislike that but we have to recognize that it's a prowess and salute the actors skills.
Plus, the chemistry between the leads was good even when they were exes so it really didn't disappoint on the romance part.
A wee bit disappointed by the OST tho. It's a mini kdrama and what we've got is not bad but it feels like they didn't put in too much effort.

Don’t judge a show by its title!
Don’t judge a show by its title—this one had me reaching for tissues more times than I can count. Every episode takes you on an emotional rollercoaster. Great storyline and the perfect casting. The actors did a pretty good job in portraying the complexities of each character. Woo Do-hwan THE MAN that you are!Was this review helpful to you?

Not for everyone especially if you're too emotional of a person.
I overall loved the series, it was built on a great storyline and amazing acting. I know it's marked as comedy drama but just proceed with caution especially if you've lost a loved one from cancer. I had a panic attack by the end of the series bc of how real everything around the person with the illness was depicted sooo yeah, it's not for you if you have a weak stomach. I wish we could see a little more of the dad and how he felt and delt with Hae Jo leaving home and him learning about Hae Jo at the end, I believe it would add a bit more to the story or well it would probably make me cry a bit more ig.Was this review helpful to you?
