i'd love it if he turned around and pointed out that he does it too and that it's totally normal.
(not that we know if he does it or not, but let's be honest here)
She’s practically told him every time some guy has dirt on her, she gets blackmailed and vaguely tells him what they try to do to her. Leaving him to just imagine what happens
i truly admire that last panel. she yells it to the whole corridor, there's no way he doesn't know what it was about. he doesn't act surprised that was what it was about, confirming he heard it. he says she was asking about it to make fun of him, admitting he could be humiliated by it. she says YEAH I WAS, admitting to planning to (further) harassing him. they are so stupid. i love this manga.
damn, he mad, prolly had enough, but i feel bad for kuchinasi too, she ain't used to be close to someone, so she doesn't know the borderline, but man, at least don't go hard on her like that,
