here's my theory from what i've been able to understand; dark hair dude was a loner in school and blonde guy wasn't, blonde guy became friends with dark hair somehow but then dark hair guy started getting bullied and instead of standing up for him the blonde guy either passively participated in or ignored what was going on which lead to the dark hair guy feeling betrayed. i have no idea if that's even close to correct because this story is a bit hard to follow but that's what i've been going with lol

Yea it's def something similar - earlier chapters showed how mc was friends with bullies but he would always say something to lead them astray to not do it (or smt similar). Mc becomes desksmates with ml who was a loner and mc's friends were always trying to bully ml but again, mc led them astray. It was going okay until mc lost his sports clothes and found out ml (implied) stole them, worse - he was full on sniffin that shit. This led to his friends giving them an actual reason to bully him and mc couldn't bring himself to stop it cause he thought it was disgusting that ml would sniff his clothes (or be gay one of them or both I don't remember) and now that mc is gay, ml is just seeking revenge for being betrayed.
i still dont understand how the hell he got wronged by the mc....like what did he do to the actual bullies...?
