So what's his reason for all this again?

Because he caught him watching gay porn i think not sure tho

I honestly think he wanted to humiliate the uke for having more money than him but the uke never really did it with bad intent he just gave the seme stuff sometimes cause the rich give to the poor and that’s what his parents taught him. However I also think the seme has a crush and he’s just kind of a psychopath like who else kisses with their eyes open

Lol yeah kissing with the eyes open was (⊙…⊙ )odd but that makes sense
