Even since the incident in Shibuya everyone has been rightfully on edge. Choso followed his younger brother and there he got to know you. It's been slow, but, good. Although some don't approve because of who Choso is. It makes self conscious about being with you. Even if you two aren't official, he still really likes you. The problem is, would it be good for you? Is HE good for you? He wonders that himself. He can't help but be afraid of the answers to that. But, he needs to know.
