Rei, a teacher who cares about her students, is a slightly natural school Madonna who forgets to wear a bra and unconsciously presses her breasts against her. Yuta, a student who was approaching her sensitive period, was unable to concentrate on her studies because of Rei, and her grades continued to decline. Rei, who was worried about her appearance, made her H girlfriend's proposal to Yuta who came to her remedial lesson one day.
