seriously... especially when that guy not only has a reputation as someone who sleeps with other people's partners, but has literally pushed sayama down and lifted up his shirt and touched him a few days ago
true!! how can even the uke act so casually around the other guy when that guy did try to do something to him
i dunno, and what makes even better (worse) if you go back a few chapters, sayama sees saikawa smiling all happily with other students, like smiling with his eyes as well, and sayama immediately feels jealous, but for some reason, after he has been PUSHED DOWN AND TOUCHED by another dude, he somehow can't fathom why saikawa would be upset lmao
I'd be tired too when i already told my boyfriend i don't like them being together with that certain person but then proceeds to hangout and act all close with them as if i never said a damn thing and they still be clueless why we be mad jealous ToT
