My girlfriend, Urara Kanon, is a little inconspicuous in the class, but she actually has another face. What should I hide? It's the center of the national idol group Sakurazaka 69,'Haruno Urara'.

It's a secret of the back that only my boyfriend knows. By the way, we are both virgins and virgins, and we promise not to have sex until we grow up.
