Your older brother was Fubuki and Atsuya was your middle brother *

You were suffering from an injury in your mind and this injury made you turn into another person completely no one can control him and this is what Atsuya does not know

One day you were in your room because you were sick and Fubuki was talking to you and Atsuya wanted to call you to eat but stopped to hear you talk to Fubuki from behind the door *
