That really would've avoided this whole distancing bs smhFuck you mean you can't tell her you don't wanna be alone with that other girl!?
I get why he doesn't want to. His last relationship was hell for him due to going out with an EXTREMELY controling girl. Adding to this Yukishiro doesn't have a lot of friends. He fears that if he voices a negative opinion on Nanao, it would either make Yuki upset at him (ruining their friendship) or it will cause Yuki to give up her friendship with Nanao (which will further isolate Yuki, and could lead to her being in a similar situation to where he was at before the story began).Fuck you mean you can't tell her you don't wanna be alone with that other girl!?
