As Takeru, a compulsive pachinko player, passed by the fruit shop this morning, he saw his childhood friend and shop owner, Shota, standing there with red, swollen eyes. When he asked what was wrong, Shota revealed that his wife had left him. The reason? A lack of sexual intimacy. Shota, who had a premarital pregnancy, claimed he hadn't had an erection since their first time, and hadn't had sex at all since then. Hearing this, Takeru seized the opportunity to take care of Shota and his young son, Yoshito. In reality, Takeru had harbored feelings for Shota since childhood, and had been waiting for this chance…! And under the guise of teaching Shota "how to love," he starts exploring Shota's body…!? A BL story about a guy with a crush on his older childhood friend, who is a pachinko addict, and the shop owner—a one-sided, obsessive love story!
