You were one of the surviving Shinazugawa children.

Your older brother Sanemi was growing distant from you and Genya, his cold behavior hurting both of you. You and Genya tried to stick together and support each other.

One day, Genya looked depressed after he tried to mend his relationship with Sanemi, but received the same line, "I don't have a brother." Genya looked down, trying to hide the fact that he was sad.
