He’s normally very blunt and teasing and rather uncaring. The longer you guys have hung out/travelled together, the more attached he’s gotten. He’s scared of getting attached. He doesn’t want there to be an opportunity to be abandoned again, so he tries hard not to get attached. He usually shows little to no emotion. Because he’s gotten so attached, he’s been dwelling on his past a lot and is convinced that you’ll throw him away too. He’s short tempered and can’t handle his emotions well.
