- The new (blonde) guy starts to bully Woohyun and Woohyun's friends basically ignore him. Especially the blue-haired one since Blondie threatened to out him if he didn't do what he says.
- MC (brown-haired girl) even starts doing things to piss Woohyun off because she likes it when he gets angry. She also starts spending more time with Blondie, but that seems to be against her will. She still wants to be by Woohyun's side, but doesn't for some reason.
- MC goes all psycho again and in her psychotic state she goes over to Blondie's house. If you guys remembers, he lives with the black-haired girl. There's some sort of violent exchange, but I can't tell what exactly is going on.
- Blondie keeps MC as a captive I think. Idek...he just has her on a leash and torments her.
- The black-haired girl goes to MC's house (idk why) and she runs into Woohyun there. He punches her in the stomach and she goes all heart-eyes for him.
- Woohyun ends up calling Blondie from her phone and is all "you took my girl so I took yours" (I think) And after the phone call it looks like she's coming onto him and is suggesting some sort of idea.
- Black-haired girl takes Woohyun back to where Blondie is and when they walk in, Blondie is kissing MC which pisses off Woohyun. His blue-haired friend is also there and so Woohyun is like "nah fuck you guys" and MC goes all psycho again.
- The next day when they're at school, Blondie and blue-hair get into a fight. After this, blue-hair finds Woohyun and they have some sort of discussion.
- There's flashbacks to the past explaining why Blondie hates Woohyun so much. It also shows how Blondie and black-haired girl met.
- Next there's just more exchanges between Blondie and MC. He still has her captive and she's getting more and more unstable.
- Blondie ends up giving MC a knife while she's going all crazy and she ends up going to Woohyuns house. Blondie follows her there.
- When Woohyun eventually shows up, he's with the black haired girl and it turns out they're now dating lol. MC goes even more unstable and stabs Woohyun in the stomach. The wound isn't that bad though.
- Woohyun and his new gf end up leaving Blondie and MC there after the gf kicks Blondie and he's on the floor.
- When they go back to school, Woohyun's friends are all buddy-buddy with him again and they end up bullying Blondie.
- Blondie meets up with MC on the roof at some point and she pretends to hug him, but pushes him off instead. He dies from the fall.
- MC gets flashbacks of her abusive upbringing with her parents, mainly her father.
- At school, black-haired girl runs into MC and they get into some weird fight.
- Woohyun along with his friends and gf are hanging out at his house. MC shows up crying and all bruised from the fight. They talk for a bit and then MC slits her own throat.
- Idk if this part is real or just all in MC's head, but Woohyun is with her in the ambulance taking her to the hospital. But while she's was in the hospital, she was having hallucinations of him being there.
- Some time has passed, I'm not sure if it was months or years but Woohyun's friend and gf are all at the airport to pick him up. He must've gone abroad to work for his dad and had just come back.
- When they're in the car on their way home I think Woohyun asks his friends to drop him off at the hospital. When they get there he gets out the car and his gf chases him. She's mad that he's not really paying her any attention but wants to go and see MC. They exchange some words but ultimately he leaves her there crying.
- Woohyun is wheeling MC around in her wheelchair in the snow. I think he says something along the lines of no one wanting his toy (MC) now that it's broken. Then it ends there.
