Aight I low-key zoned out the whole time I was reading this wtf is happening help a dumb b...

WARNING SORRY IN ADVANCE THIS IS LONG IDK WHY I WENT ALL IN ON THIS AND I DEF GOT SOME THINGS WRONG CAUSE I'VE BEEN READING CHAPTER BY CHAPTER SINCE IT WAS RELEASED.

SEASON 1 starts with Yuwon (Brown Hair) working an office job. He's miserable, everyone at his job treats him like crap. He only has one friend Seongmin (Blondish Hair). Then one day, their told a new manager who's an heir to the company is going to start working with them, that man is Dohun (Dark Bluish Hair) and turns out Yuwon and Dohun go way back and were close in high school. As Yuwon remembers, Dohun was horribly bullied and Yuwon defended him. The 2 got very close and had a romantic relationship basically. But one day out of the blue after the students who were bullying Dohun mysteriously died, Dohun disappears without a trace, leaving Yuwon with a million questions. The rest of season 1 is Yuwon and Dohun reconnecting while working together and Dohun seemingly invading Yuwons life out of nowhere after not seeing him for over a decade. Seongmin is the only other person Yuwon is somewhat close to, and is shown to be a good friend who treats Yuwon kindly at work and takes care of Yuwon when he gets too drunk while out drinking with coworkers. Dohun clearly dislikes their friendship, as Seongmin offers to let Yuwon move in with him when Yuwons landlord demands he moves out suddenly. Instead Yuwon moves into a large home with Dohun. Yuwon remembers Dohun as a weak, bullied, and poor kid, him suddenly being wealthy and a man of power at their job, confuses Yuwon to no end. Dohun offers Yuwon little explanation, only claiming they are destined and that he wants to take all of Yuwons unhappiness away and live together. The season ends with Yuwon realizing they cannot be happy together, and deciding to quit his job and leave town, as well as his relationship with Dohun. He tells Dohun all of this and Dohun freaks out and attacks him, speaking nonsensical words about them being in love and destined for one another. He rapes him, beats him, and carves his name into Yuwons side. The season ends with Dohun telling Yuwon they must return to their high school days, when they were in love.

SEASON 2 takes place in the past from Yuwons memories, back when he first met Dohun (I believe they were 17 or 18, don't know for sure but they were in high school). Dohun is a new student and is quickly bullied for acting strange and almost robotic. Yuwon defends him and although Dohun is off-putting, the two quickly become close. Yuwons parents died when he was very young and is living in group home where he is abused. He tells Dohun he wishes he had his own home (I think thats what he says can't remember) and suddenly, Dohun has a home. It's rundown and small but Yuwon starts to stay there often (From what I remember he runs away from the group home). Dohun seemingly has no family and they grow even closer and fall into a young love. But suddenly one day, Dohun disappears, and on top of that, his bullies have all died in strange accidents. Yuwon can't help but feel like Dohun killed them, especially after a chilling conversation they have, where he basically admits to it. After Dohun disappears, Yuwons life blurs. He moves back into the group home, graduates, and grows up, spending years haunted by Dohun's ambiguity and disappearance. Now back in the present at the end of season 1 Yuwons memories begin to shift, and the readers realize Dohun was never bullied, Yuwon was. As we see this realization, we are shown Yuwon being hit by a car sometime after graduating high school (I believe). Dohun then tells Yuwon what he feared, Yuwon never had friends, Dohun was never bullied, when he was hit by a car, the accident made his mind shift the narrative and there places in it. (Or this could be due to his own mind protecting him from suffering anymore, or both I'm not totally sure) Its also implied Yuwon might've killed the bullies himself. Now being back in the present, the end of season 1, Dohun lifts his shirt to reveal he has Yuwons named carved in his side, just like he did to Yuwon. He tells Yuwon they have to stay together, because they are destined and the season ends with us getting a flashback to the first time Yuwon and Dohun meet again at their place of work in season 1 (Implying said destiny)

SEASON 3 (Freshest in my mind so this one is the longest sorry I'll space it out in paragraphs) starts off with a narration of a children's book. The book is about a deer trying to find his destiny in life. We are shown that the person reading the book is Dohun as a young child, he asks his mother what Destiny is, his mother is clearly not stable and all we are shown of her is a black silhouette crying and shaking. Soon after, he is taken away from her to live elsewhere in a basement, he learns basic things there, how to eat properly, how to change clothes, and other everyday tasks. A man teaches him these things, never offering nurture or anything beyond lecture, this man is Director Jin who we learn works for Dohuns father.

The story introduces Dohuns older brother Hanseob, a deranged and sick man who insults and beats Dohun, claiming he should be the only child of his father since Dohun is an illegitimate child, and they don't share the same mother. Whenever he asks the man from before any questions about his brother or family, he is dismissed and quickly adopts the attitude that he is alone and shouldn't bother asking questions. The only thing he could find any sort of comfort in was his book, where he became obsessed with Destiny and finding his own.

After years of being beaten and brainwashed one day Hanseob puts him in a suitcase and takes him outside. We see another piece from the children's book where hunters are attacking the deer, but they are stopped by a large tree, that protects the deer. We then see Dohun leave the suitcase to find himself in a bathroom, having been left there by his brother. He leaves the bathroom and finds himself at a public park. Soon after he sees children talking, one of them being bullied and told to go buy them snacks. Dohun takes one of the kids snacks and starts eating it, the bullies attack him, but the kid from earlier who bought the snacks intervenes, getting his himself. He begins to cry, and its revealed the child who stepped in was Yuwon. Dohun hugs him and thinks about his book and destiny viewing Yuwon as the tree and himself as the deer. Yuwon shoves him off and blames Dohun, saying he shouldn't have helped him and runs off. This sparks Dohun's obsession with Yuwon blaming him for all his suffering, wanting to take on all of Yuwons pain as his own so Yuwon can be happy. Dohun thinks about Yuwon over and over, believing Yuwon and making Yuwon happy to be his destiny.

When hes returns to where he was before the park, we meet his father and learn that Hanseob is a drug addict and a disgrace to their father. Dohuns sole reason for being there is being a backup in case Hanseob continues to fail at being the heir his father desires. It's also shown that Dohun's original name his mother gave him is not Dohun, and so far in the story we don't know it. His father renames him, and we are reminded that Dohun never had the chance to tell Yuwon his name when they met at the park. (Could be remembering this part wrong)

Hanseob burns Dohuns book, claiming he never wrote his name in it, so it wasn't his. (This draws back to Dohun carving his name into Yuwon, and carving Yukons name into himself, also another scene where in high school Yuwon gifts Dohun a flower pot, and Dohun writes his name on it) Hanseob rapidly shifts his behavior towards Dohun, beating him and verbally abusing him, and than asking for Dohun to comfort him and confiding in him about his struggles with their father. For years he thinks only of Yuwon and their destiny together. Now being a teenager, his father tells him he is going to start school where he meets Yuwon again. Yuwon doesn't remember Dohun, having such a small interaction with him and never learning his name, while all Dohun had to escape his reality was his memory of Yuwon.

We start to see Yuwon being brutally bullied at high school, the true nature of the past finally being revealed through Dohun's perspective. Dohun begins to intervene and little by little inch his way into Yuwons life. Yuwon begins to open up to Dohun and Dohuns take this as proof of their destiny, and Yuwon needing him. Its eventually revealed that Dohun killed Yuwons bullies, possibly with the help of his father. We learn the reason for Dohuns disappearance was him wanting to become successful so he could buy a home and live with Yuwon in the future. This takes over a decade of Dohun working his way up in his father's company, all the while doing it for him and Yuwons future.

Now back in the future, we see the events of season 1 through Dohuns eyes. We learn that Seongmin is far from a good friend, and possibly takes advantage of Yuwon when he gets drunk and passes out. Dohun discovers Seongmin jacking off at Yuwons desk and confronts him, having had a a secret camera installed there to watch Yuwon and catching Seongmin in the act. He tells Seongmin to leave town without a trace, he does, this causes Yuwon to believe Dohun killed him (Something mentioned in season 1 forgot to write it there). Hanseob is basically cast aside by their father, having used up all his chances in their father's words, Dohun has him in some sort of room and we learn the person who hit Yuwon with their car was Hanseob. Dohun also has a conversation with a work superior of Yuwon who always mistreats him. It's a very long scene that we constantly get flashes back to, but he basically threatens him and makes him eat fish eyeballs to pledge his loyalty to him (I'm getting lazy describing things now). The latest chapter ends off with us meeting a new employee at the company, a woman named Jiyoung. (Some comments are saying she's a new character but I feel like I remember us meeting her back in season 1 for a bit and her being kind to Yuwon before suddenly ignoring him probably due to Dohun threatening or manipulating her but this could just be another employee)

ANYWAY sorry for this, I would def pull a "not reading all that". I left out so much despite how much bullshit I wrote cause this story is so complex, very long, and I haven't re read any chapters so my memory isn't great. Hope I could be of some help!

Yeah I remember now thanks
imstill highkey confused with dohuns pov because I cant distinguish who the dad the brother and the grandpa was (if there even was a grandpa) because for me they all act the same and ofc face blindness and shit
