I forgot

If with blond you meant the MC, we still don't know since the blond forgot (due to his memory lost) what he do to the black hair dude. Also the black hair dude refuses to tell him what happened so we haven't got to the explanation part of the story lol.

we don't know the full story but basically the blonde and ml were dating and he forgot everything (due to the accident) so the ml is mad he forgot about him. in terms of what he did we only know the ukes pov which aint much but hints he was kinda rude to the ml sometimes, and both were abused.

I saw the raws and the blonde guy pushed the uke and cause an accident that made him forget his memories and cause his body to stop growing that’s why he hasn’t changed and the blonde dude is obsessed with the seme (I think their like step brothers so the seme doesn’t want him or something) and he did that to the uke to get him out the way and make him leave the seme when they were younger but the seme doesn’t know what happened that’s why he treats the uke like shit trying to get revenge

Oh gods aw ╥﹏╥

but like why does he do that i feel like something is missing in-between
he got into an accident and forgot him but like didn't something else also happen?

Yeh I think after he forgot about him there was an incident in school with bullies or something and the uke sided with the bullies against the seme but the accident happened when the seme was away I think so he didn’t realise what had happened and felt betrayed
