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...

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.

Annoyed that Hana and Shinichi's relationship has not moved forward, Ami and Sakaki decide to shake Hana out of her confident attitude by telling her she might lose Shinichi to other women if she lets her guard down. While teaching Shinichi to cook croquettes at her house, Hana is still bothered by her conversation with Sakaki. Meanwhile, her mother once again misinterprets Shinichi's intentions when he asks what is her first name. The croquettes turn out really good though.

The café owner and Ami encourage Sakurai to take a downhearted Uzaki to a fireworks festival in an attempt to get things back to normal between them.

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.

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.

Sakaki convinces Hana and Shinichi to attend the college's festival, bribing them with the opportunity to win a video game console in a lottery. On the first day of the festival, they actually have fun together and decide to have their fortunes read at the Occult Club's stand. They then try to leave when they discover that only romantic fortunes are told, but are forced to comply. Shinichi is left emotionally shaken after he hears their fortune. Later, Hana prepares a meal for Shinichi and herself. She concludes via a self-absorbed thought process that he needs her around and tries unsuccessfully to get him to say it.

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.

College junior Shinichi Sakurai just wants to be alone, but loudmouthed sophomore Hana Uzaki sees it as her mission to keep him from being lonely.

Sakurai’s friend is determined to get him and Uzaki together, but meets resistance from an unusual place. Uzaki has some thoughts about choco-mint.

An innocent trip to Tottori soon becomes a calculated effort to turn Sakurai and Uzaki into a full-fledged couple. After all, Tottori is for lovers!

Uzaki starts her part-time job. Sakaki orchestrates a summer getaway for the four friends, including a fun day at the beach and a spooky night walk.

Turns out the café-owner’s daughter Ami loves people-watching, too. Sakurai comes down with a really bad cold. Uzaki has a big request for her senior.

Uzaki tries to get Sakurai out of the house over the extended Golden Week holiday. A crowded train takes Sakurai someplace he doesn’t want to go.

Uzaki visits the café where Sakurai works, much to his dismay. An encounter with a cat goes horribly awry. Sakurai eats lunch with an actual friend.

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