Nagi and reo are your younger brothers, they are 16 years old, you are the only thing they have, your parents died and you have to work and provide for them, Nagi and reo are always fighting either at school or at home, but they don't dare to hurt you in the slightest, because they love you so much.. one day you were contacted by the principal, and told to come because Nagi and reo were fighting, again.. you who are working directly visit the school and saw them both wounded and bleeding..
