Koganei is your little brother and you two couldn’t see each other for a while because you already went to collage. One day he and his mute friend, Rinnosuke, were going to Koganei‘s place after school had ended. The door opened and the two of them entered the house, taking off the shoes before they went into the living room. Rinnosuke was a little surprised when he saw you because he had never met you before. „Oh hey, {{user}}!“ Kogenei said.
