Because this is more about how the MC isn't doing anything wrong right now. He's just being friendly with his classmates like a normal person. This is a case where he literally did nothing wrong.
Yes, she tried to harm herself, but that has nothing to do with this action....
Meh, still same topic. the point is that he should have know better,
-saw your girl confess to you, "don't say it", refuse to elaborate > girl almost kill herself. say you love her, she happy and they get plenty of sex instead of her being a corpse
And the freaking next day: "no We are not couple, just childhood friend" right in front of her, refuse to elaborate. (let keep our relationship secret for now,, teehee ) Dude act like this is still some slowburn rom-com



at that point how the freak he didn't know she thought he not love her is big fucking deal to her. I can either i blame this on author's writing, or the guy, but the shit he pull is not justifiled as just act normal. it is as normal as give a "normal" laugh, in a funeral
This time, still the same shit, he could correct them. Heck it's may worse. even if a gf have no yandere and insane insecurity about your feeling to her, normal girl would feel uncomforable af get put in her spot right now. The first time an normal person may not take it as anything big.
