@Uyamikun I'm certainly annoyed by his chain smoking habits, but I keep hoping he would stop. Perhaps he would realise he's not hurting only himself (which is not an issue for him; he doesn't care), but he's also damaging Mayu. Right now he's pretty antisocial and thinks nothing of other people, but if he reaches a point where he starts to think about it, it also means he's healing from the traumas caused by his broken family.
