Introverted otaku Akiyama was perfectly happy living alone, but overly friendly gyaru Nakamura suddenly barged her way into his apartment and his life. Akiyama never imagined finding domestic bliss with a person who is his exact opposite, but now they're cooking for each other, buying furniture together—basically everything a normal couple does. Are they a couple? Before the two can figure it out, a potential rival appears: Utena-san, who plays online games with Akiyama and has far more in common with him. The stakes are heating up in this cute romantic comedy!
