It tells the story of 25-year-old Li Jen Yao, who turns himself in for a series of cold-blooded murders and admits to being the serial Rainstorm Killer, who once terrorized his high school classmates. While he reveals the grisly details of his crimes, he never discloses his motive. In prison, he grants his first-ever interview to Chou Pin Yu, only for her to become entangled in unsettling dreams of both the killer and a mysterious girl in uniform. As dreams and reality intertwine, long-buried secrets of love, hatred, guilt, and redemption resurface. (Source: Netflix) Edit Translation

Romeo and Juliet.. But The Tortured and Murderous Kind..

First things first, this is not an easy watch.. It’s honestly an unpleasant drama to get through.. A lot of what happens here hurts you, breaks you and makes you want to break into the screen and take matters into your own hands.. Had I Not Seen the Sun embodies what a drama exists for, not just to tell a story but to immerse the audience completely.. The drama doesn’t try to entertain.. It just deeply affects us, shaking, frightening, unsettling, disturbing and jolting us.. It makes you feel the weight of what’s happening, not as fiction but as something real and close and that emotional discomfort is what the drama uses so effectively.. Simply put, Had I Not Seen the Sun has the power to shake you up, terrify you and leave you in a bewildered daze by the time it ends..

The director doesn’t soften any harsh realities, violence, cruelty, moral decay.. The drama is honest and in some ways even nihilistic.. It reveals the ugly, disturbing aspects of its subject matter in a sharp, precise way..

There is a lot to talk about here, but I will try to keep it simple.. The whole story unravels in the best possible way, starting with a gripping first episode which is intriguing, sharp and setting up the psychological thriller vibe perfectly.. The drama has a lot of little details in the present timeline about Chou Pin Yu that you might miss if you are not paying close attention, the mirror, the bag, the phone in the first episode, for example.. All of it quietly hints that everything is not as it seems..

I liked how the story shifted between the present and the past and that transition from past to present in Episode 2 was just wow.. The screenplay is ambitious in its framework.. It’s not just a serial killer story, but a character driven tragedy with real psychological depth and a touch of tragic romance.. I also loved the moth-butterfly-sun metaphor, especially the way the drama shows Li Jen Yao as the moth drawn to Chiang Hsiao Tung, his sun.. And Chou Pin Yu’s hallucinations are equally intriguing, they almost give the drama a supernatural feel even though it’s all happening in her mind..

The cast was actually perfect.. Tseng Ching Hua was just outstanding, his expressions, his presence and that calm menace, it was all so eerie.. Moon Lee as Chiang Hsiao Tung was the emotional core of the story and she was painfully convincing.. Chiang Chi as Chou Pin Yu didn’t get a lot of screen time.. Her performance was intriguing enough that it actually made me even more excited to see what she will do in the next part..

The cinematography is beautiful, in the most absolute sense of the word.. It has some seriously good visuals and color tones.. And the framing, the symmetry, was well structured and looks great on screen... And credit to the OST too, the music played such a huge part in setting the vibe..

One small detail bothered me.. Someone that meticulous, someone who didn’t want the FL linked to his crimes in any way, somehow left that one photo lying around?? That should have been the first thing he destroyed, I wonder why he missed that..

Overall, Had I Not Seen the Sun is a seriously good drama that you just can’t overlook, with a cinematic level of screenplay and storytelling.. It’s not an easy watch in any sense.. But if a drama can pull such an overwhelming reaction out of you, then it’s doing something right, isn’t it?? I actually thought these 10 episodes might feel draggy somewhere in the middle because there’s a Part 2 coming.. But not at all.. It’s very well paced and not bloated in any way..

Part 2 is where all the revenge is.. Hope they don't hold back and go all in, brutal, bloody and unapologetic.. There are still so many unanswered questions.. What’s the real identity of Pin Yu?? I thought she was the FL but then who is the girl at the end?? Ko Chia Yen’s character?? If she is the FL, then having three different faces for the same person feels a bit too much.. But I do have a few other guesses.. Let’s see.. Either way I am excitedly waiting for Part 2 and hoping it ends on a harsh, bloody note.. And yeah, I don’t want to debate whether his actions were right or wrong, they were scum, rotten to the core, they had it coming, every last bit of it..

I am expecting a stripped down, bare bones, no nonsense, brutal revenge story for Part 2..

Because I hate the rain.

Had I Not Seen The Sun Part 1

I was halfway through episode 6 when I noticed that this is only part one of the story. Had I'd known the season was split, would I have waited for the other half? Probably not, as I added it to my watchlist just for the beautiful title and the fact that it starred Tsenf Ching Hua as a serial killer. They had me hooked right then and there, I was waiting eagerly checking that countdown days, hours, minutes. I know Netflix added that feature to tease impatient people like me.


The story of a man that chops up people into pieces shouldn't be this beautiful, but it is, it is so beautiful that I kept forgetting that he is a cold hearted murderer and when I did remember I wanted him to be innocent so badly!!

The cinematography is stunning, the soundtrack is hauntingly beautiful, the cast is amazing,the symbolism of the moths and butterflies and the delightful manner in which he explained to her how they're different.

A man who killed people in such a gruesome way shouldn't be this relatable, but he is; I couldn't help but fall for him and that's where the plot faltered, too much time was spent in that backstory making this cold blooded killer far too sympathetic, far too human so Be warned if you're thinking of watching this, I may emphasizing the beauty of it all but at it's core this is a horrifying story, it isn't romance, it's not all sunshine, rainbows and butterflies It's about a series of gruesome murders and the events that led this man to commit such heinous acts of violence are gruesome, awful, vile so hard to watch and they're not afraid of showing how bad it was.

I had gut feeling, that something else happened, there's something the plot is hinting at that made me form a theory that the preview of what's to come have sort of spoiled/confirmed.

December 11 come quick because I need to know!!!
