Gesu no Ongaeshi

Manabu is a pervert that aces every subject in School. He is childhood friends with the star actress Mirai and doesn't waste a single opportunity to flaunt his past childhood friend relationship with her in front of his friends. But when he is asked to tutor her in her own room, can he control his pervyness and help her childhood friend out? Or will something bloom from their rekindled friendship?
