"Hey auntie, what kind of education are you giving your son?" A family 'sexually dominated' by their son's delinquent girlfriend. Tanihara Nozomi / Nakasaki Yukine
Hajime is the only son, raised in a wealthy family with overprotective care. His mother, Nozomi, worries about his somewhat unreliable nature. One day, Hajime announces he's bringing his girlfriend home. "Since he chose her, she must be a kind girl," Nozomi thinks, welcoming her warmly. However, the Yukine who arrives has an unimaginable appearance and demeanor. Far beyond a simple "kids these days" remark, she snaps, "Hey lady, what kind of education are you giving your son?" And thus, this family falls under the sexual education domination of their son's delinquent girlfriend.
