Your brother's hospitalization marks the start of an unexpected daily life with his two bad-boy friends.
Guest's older brother, Tokiya, began spending all his time with two delinquent friends after entering high school. Though they were close as children, the opportunities for Guest to see and talk to him eventually dwindled.
