Yokodera Youto is always thinking about his carnal desires, but no one acknowledges him as a pervert. He learns about a cat statue that supposedly grants wishes. The boy goes to pray that he will be able to express his lustful thoughts whenever and wherever he wants. At the statue, Youto encounters Tsutsukakushi Tsukiko, a girl from his high school with her own wish—that she would not display her real intentions so readily.

As Yōto takes Tsukiko to an animal café to discuss their next move, they coincidentally discover that Azusa is working part-time as a maid. They intend to approach Azusa following her shift, but are forced to flee when they are reprimanded by a janitor for taking shelter from the rain near a love hotel. However, they soon find her working at yet another part-time job, later discovering she lives alone in an apartment. After Yōto confronts Azusa about this, he asks her on a date to get her away from work, with Tsukiko deciding to follow them. However, Azusa is less than happy with Yōto’s choices for date venues, so Tsukiko steps in and they instead her to an arcade, where Tsukiko wins Azusa a stuffed turtle. Despite managing to get along, Azusa gets a bit upset when Yōto brings up the topic of friends. Just then, the track and field president and Tsukiko’s older sister, Tsukushi, shows up, forcing Yōto and Tsukiko to flee when she enquires about their ‘date’.

While a sick Tsukasa is being treated by the younger Yōto, the young Tsukushi, along with Tsukiko, agrees to visit their mother once again after Yōto persuades them. At the mansion, the young Tsukushi and Tsukiko wear the clothes their mother made by hand. Knowing that their mother loved them, the young Tsukushi laments over wanting to have memories with her mother. The younger Yōto reprimands Tsukushi, but nonetheless, gives her his precious memories with Tsukasa for their sake by wishing to the cat god, resulting in the current Yōto forgetting all about meeting the Tsutsukakushis and Emi in the past. Meanwhile, Yōto and Tsukiko return to the present. After heading back to the mansion, Tsukushi decides on not going to Italy and afterwards, Yōto and Tsukiko share a kiss. Days later, Yōto, along with Tsukiko, Tsukushi, Azusa, Emi, and Mai have fun at an amusement park.
