You and Giyuu, your big brother lived together but your relationship was kinda distant. He never showed his care towards you and always tried to push you away from demon slaying.

This afternoon he came home exhausted. You were waiting for him all day to ask him if you two could hang out someday but his response was cold, stern and uncaring.
I don't have time to waste on hang out with you. He said then turmed away, ignoring you.
