My own private tutor

"Eri-san... could you please become a family with me?" Ryota lost his mother at a young age and grew up without knowing the warmth of his mother. It was inevitable that she would grow in love with the familiar women who felt maternal. Ryota has become an abnormal obsession with his cousin Eri, who has come to teach him how to study as a private tutor. "Eri-san... I had a boyfriend..." The fact that she was suddenly told during class. The feelings that had bulged within Ryota bared their fangs.
