The unlucky student was noticed by the beautiful teacher.

Rei, a teacher who cares about her students, is the school's slightly self-conscious Madonna, forgetting to wear a bra and unconsciously pressing her chest against her. Yuta, a student who is entering a sensitive period, cannot concentrate on his studies because of Rei, and his grades keep falling. Seeing this, Rei gets worried and makes a naughty suggestion to Yuta when he comes to tutoring one day.
