So from what I could tell, mc and ml had a sort of fwb relationship in high school. They both caught feelings for each other but this was never said directly (sadly). When mc saw ml kissing another guy (who was probably his step bro), mc thought ml was just playing with him and felt rejected for having one sided feelings.
Feeling hurt, mc distanced himself from ml and pretty much broke off their friendship. Having feelings for mc, ml felt betrayed and has been angry and wanting revenge against mc for breaking his heart.
Their both still down bad for each other but of course their way of dealing's thru miscommunication, misunderstandings, and mind games.
HELP MEEE !! can someone explain me why the seme is acting that way or rather what happened between uke and seme in the past to now because I read it while mixing up the chapters and everything so I don’t want to read it again
