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. Kiri is dismayed to learn that the maker of the udon he had enjoyed is male, while Yanagi is highly amused by it all. Meanwhile, Shinichi tries to sweat out his Hana-induced inner turmoil.

At the gym, Fujio shares his worries with Shinichi and two other regulars about his daughter having a boyfriend. Since Shinichi spends so much time training, Hana feels neglected by him and reiterates that he is the one who likes her in response to Yanagi's teasing. The next day, still under the delusion that Shinichi has feelings for her, Tsuki spends time at the café and leaves him alone with Hana for his cooking lesson, in the hopes their relationship develops. Later, she bumps into him on her way back home and erroneously believes he and Hana had sex. On November 29, Hana spends time with Shinichi for his 21st birthday and he privately acknowledges she is special to him. Meanwhile, she realizes he will graduate from college in a little over a year, and requests he do something outrageous.

Hana is worried she will not be able to hang out with Shinichi once he graduates from college. Since she is adamantly convinced that he likes her, and not the other way around, she plots to make him confess his feelings to her. She cooks him lunch, which attracts the interest of her whole family. After Hana refuses to introduce her to Shinichi, Yanagi visits the café.

Hana has a meltdown at the café because Shinichi does not call her by her first name, although he does with other people and he called Yanagi by her first name not ten minutes after they met. Back home, Yanagi tells her mother about her meeting with Shinichi, making Tsuki spiral down into further misunderstandings. Kiri is stressed studying for exams and lack of physical activity. As such, he goes to exercise at the gym where his father works to cheer himself up. However, when Shinichi also shows up, Kiri ends up feeling completely outclassed.

The Uzaki family go to a hotsprings resort, minus Kiri who is still traumatized after running into Shinichi. Fujio reminisces of the days when Hana was a child, and soon after arriving at the resort chases off guys hitting on Hana and Yanagi, and then Tsuki. He then gets surrounded by young men admiring his physique, which turns into a photoshoot as he basks in the attention. While the cat gets training from the resort's mascot, Hana goes wandering and runs into Shinichi and Sakaki. She offers to hang out with them but Shinichi tells her to spend time with her family. As they part, Hana gets Shinichi to compliment her bathing suit. Back to the Uzaki household, Kiri regrets not having joined his family's outing, while a now buff cat scares a bunch of the neighborhood's kitties.

Tensions are high between Sakurai and Hana as the lovers' holiday of Christmas approaches. Sakurai gets a shock when he touches base with his family.

Hana reminisces about high school with Sakurai while his father warns him about their relationship. Sakurai gets solid advice from an unlikely source.

It's Christmas Eve, and Hana finds a way to spend it with Sakurai at her home. He's introduced to her father Fujio, who knows him from somewhere...

Christmas Eve at the Uzaki house comes to a confusing end for just about everyone involved, leading Sakurai to reexamine his feelings for his junior.
