i rlly feel like he did that so misaki would have the mindset of being gay. I THOUGHT KEIICHI LIKED MISAKI FOR A SEC I WAS SO SCARED bakugosbitch
that's probably the reason and it worked somehow lmao??? also i'm glad the author didn't make keiichi interested in misaki since the jealous best friend trope always ends up badly and keiichi seems like an actual cool guy
i like how we're all collectively ignoring that keiichi highkey implied haruto was the one who spread the rumor of him dating misaki
