Here but it's in Korean so you have to turn on translation options in chrome to read in your language

Ok so spoilers: the real reason he even first approached this MC is cuz he saw him way before their first meeting, getting beaten by the guy from the first chapter and thought uke would look better in cum than blood over his face, disgusting I know... He made a bet with the other guy I think the white haired one that who over gets to sleep with the MC first would win, now I'm not sure if they're talking about fucking him over or what cuz the translations from Google are messy anyways The MC gets to know this later on by the old guy that used to beat him before. He gets super angry and heartbroken. He confronts ML. Now the ml says he's over the bet and he loves him a lot but obviously the uke doesn't want any of it. There is so much fighting in this it just keeps becoming heavier. the ml is way too obsessed with MC and even chokes him and beats him up. The white haired guy also gets badly beaten up just cuz MC sat with him after the confrontation and not the ml. Like this ML is a big ass crazy motherfucker.

To answer how's he so violent, Idk what to say. At one point after the confrontation the uke says things that hit the seme's weakpoints I guess and the seme gets so angry and says he doesn't like the uke anymore and says he'll idk how to say like toy with him until he's done.he makes him sit alone and he doesn't like anyone getting near the MC but made his life a living hell. The other guys at school started to call the MC a faggot and whatnot. The MC is quite strong minded at the start and takes it all and fights with them as well so that was kinda satisfying. But at one point he just couldn't take their words anymore. Like he slowly starts to wither away, feels way too sick. And wants to leave everything.
After all of this, the MC tells the ml that he wants to die and go to his dad who's already passed away. He tells the ml to kill him but the ml can't do that cause he still loves him a lot. Seme then says he will let go of him now. And says he's sorry for hitting him, abandoning him, for hurting him with hurtful words etc etc. this makes the MC finally breathe comfortably again.
What happens after this, that I don't know, I still have to finish it. This has 10 chapters and 2 side stories and I still have like last 3 chapters to read. I only read the first 9 chapters with seme's point of view.
I was reading the novel and dang this is so toxic and messy. I honestly hate the ml
