Makoto and Yura Onoda are a newly married couple with no sexual experience. Yura is a shy, naive 25-year-old woman whose attractive appearance draws men's attention, which she dislikes because she gets embarrassed very easily. Her husband Makoto is the same age, but unlike his wife, he enjoys having dirty thoughts about other women. Physically, however, Makoto remains truly faithful to Yura. Although both are virgins, now that they are married, they are ready to explore the world of sex, "practicing" as often as possible. However, the world of sex is complex, so they need all the help they can get to navigate it. Fortunately, their friends, acquaintances, and porn media lend them a helping hand.
