Hentai Ouji to Warawanai Neko.

Synopsis

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 take her to an arcade game center, 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 inquires about their 'date'. When they return to the game center, they discover Azusa being tormented by some girls from her old school, leaving her cold towards Yōto and Tsukiko, believing them to have strung her along.
