Summary: ❤️❤️❤️ [WorldPG] Kaoru and Kyoko are now married. His wife, Kyoko, is more than a decade older than Kaoru, and has a child named Kayo. As a father, Kaoru tries to get closer to her, but is worried that Kayo, who is of marriageable age, won’t accept him. One day, Kaoru learns that Kayo has a boyfriend and is planning to have sex for the first time soon. However, Kayo has little knowledge of contraception, let alone pregnancy, so he decides to give her sex education so that she will have proper knowledge of contraception. Then, Kayo says, “But if we’re going to do it someday, I don’t want to fail with my boyfriend… Father-in-law, let me see your private parts for now. This is sex education, right? I should know how it works, right?” And so, with this one word as a trigger, their relationship begins to change little by little.
