well, nobody else really cares about him for him, either. C.C. is a fucking enigma; who knows why the fuck she needs him alive? But at least she's always there to save his ass when he's in a tight spot. His sister loves him just as much as he loves her. Everyone else is just depending on him for various reasons, either as a messiah, a crush, a messiah crush, etc. He treats them as well as they deserve.
