* Based on Mitsuba and Ichijinsha's 30-sai no Hoken Taiiku (Health and Physical Education for 30-Year-Olds) guidebook. The guide is aimed at men in their 30s who have not experienced romance or sex with women yet.
Imagawa Hayao is a 30 year-old virgin bachelor. One day, a "cupid" descends from heaven with the express purpose of forcing him to "graduate" from virginity. Thus unfolds a pure love story between a 30 year-old bachelor and a 30 year-old bachelorette.
