30-sai no Hoken Taiiku

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.
