Idk. This manhwa really irks me sometimes. I understand he's changed, and that the peeps around him are worried / uncomfortable. But like, dude, u guys are the ones who accepted that he "lost his memories". Yet they keep blaming the guy for not remembering. Where did their common sense go? If they don't like the new him, they could've expelled him from their lives, or adjusted by rejecting that he is their son / brother / friend.
I don't really like the fact that he's taking it in either. I know he's trying to change, and he's getting influenced by his body... But still. There could've been more char development to warrant it, rather than being so cringe teetering back and forth.
