I really need help finding this manga I read it was set in school life setting and the main character was pretty much had a really asshole personality and he had this idiot friend that had a more friendly, bubbly personality and he has romantic feelings for the main chatacter and they end having sex(?) i think in the bathroom and turns out that the friend was crazy and he threatened to kill the main character through choking him when his feelings weren't returned or something like that
i think the main character had dark, flat hair where as his friend had light messier hair
if someone can tell me the name of this manga it would be great! thanks so much!
