Uzaki-chan wa Asobitai! Double

Synopsis

Hana is upset that Shinichi calls other women by their first name but not her. Shinichi gets a coupon for a gym's free trial, and meets a trainer named Fujio. At the Uzaki household, it is revealed that Fujio is none other than Hana's father. He calls a family meeting when he finds out that her senpai, who he had assumed was a girl, is in fact a guy. The situation escalates when Hana defends Shinichi to her father and younger siblings. Her brother Kiri is dismayed to learn that the maker of the udon he had enjoyed is male, and her sister Yanagi is highly amused by it all. Meanwhile, Shinichi tries to sweat out his Hana-induced inner turmoil.
