Holy shit, this is totally the justification a bully would use XDI find it wild everyone hates Hebikawa this much lol
Everyone hates this chick for being you know a person? Her words is the reason the MC changed himself for the "better" which gives him confidence, he's changed so much that Hebikawa didn't realise he was the same dude.
Hell if she didn't even remember the previous him, her insults to him were of just that of surface level.
MC is being a bitch, took it to heart but that is who he is, and thats how hes been affected and made it a trauma, he was a loser and still has loser tendencies which hes working on.
What Hebikawa said wasn't even that bad MC just took his feelings to the extreme because he was fond of her. I don't even see Hebikawa that much of a bad person pretty everyone in their life has talked shit and not realise how much it affects a person lol
"Why are you complaining?? I made you better! Besides, it's not like I said anything that wasn't true! This is a you problem."
Hahahaha xD
