Plot
On their train to school, Yuuki and Taisuke discuss the upcoming school festival; Yuuki's class will be doing an exhibition on Sakakino's history while Taisuke's class will be doing a maid café. Taisuke then teases Yuuki about his "relationship" with Hikari, which earns him a punch from the latter.

In the meantime, Yuuki has been helping his sister with the basketball team's website, which has kept him up late at night. Upon arriving at Gakuenmae, Youka asks Yuuki to talk to the team's captain about the website, but due to the tensions within the team, Shibukawa won't discuss anything with Yuuki. Additionally, Kotonoha claims to be in a hurry when Yuuki wants to talk to her about Makoto; and Roka, still misunderstanding about Hikari, refuses to speak to him, leaving Yuuki to comment to Taisuke about "tasting life's hardships".

After finishing up the basketball team's website in the library, Yuuki goes to look for Shibukawa, but without success. He briefly considers clearing up the misunderstanding with Roka, but decides to focus on informing Shibukawa about the website after class. After class, Yuuki goes to the basketball team's locker room, only for Nanami to inform him that the team captain hasn't been there. Frustrated at this, as well as Ion's continuing refusal to help him look (with no "strings attached"), Yuuki decides to give up for the day.

The next day, the subject of Makoto and his girlfriend comes up between Yuuki and Taisuke, causing Yuuki to be concerned about Kotonoha (not knowing that Taisuke was referring to Sekai). The two go to lunch, where they're met by Chie and Youka. At Chie's insistence Yuuki, accompanied by Taisuke, goes to the library to retrieve the handouts he'd left there to give to the basketball team. Unbeknownst to him (or to Kasannoin), Taisuke writes love notes on a few of the handouts, one of which Yuuki finally manages to give to Shibukawa. Upon seeing Yuuki's "love note", Shibukawa takes Chie aside to make amends with her and to inform her that she'll help with the "break room".

All the while, preparations for the festival continue. Roka, Ruka, Natsuki, and Otome are discussing their respective break rooms, with Roka pressuring Otome to progress on her class's break room. This prompts Otome to in turn pressure Kotonoha, blaming her for the tough spot she's been put in. In Makoto's classroom, Taisuke, Ai, and Setsuna express worry about people skipping out during the festival.

After school, Kasannoin accompanies Yuuki to the bakery he frequents, wanting to buy his younger sister a cake. While there, Kasannoin introduces Yuuki to Hanon Nijou and Niki Ookuma. Despite his initial reservations, Yuuki decides to accompany Niki to a hotel, witnessed by Hikari.

Meanwhile, as the girls' basketball team works on their break room, Chie and Roka discuss the latter "dating" Makoto and Chie concludes that she should tell Yuuki to move on with another girl.

At the hotel, Niki, while taking a shower, brings up the subject of payment, causing Yuuki to realize that this was to be a "compensated date", and he runs out of the room, much to Niki's frustration.

After the basketball team calls it a night for preparations, Chie, Youka, and Ion discuss Shibukawa suddenly changing her mind about the break rooms, speculating that her change of heart was because of her having an admirer. They also discuss Roka and Makoto, and Youka agrees with Chie that telling Yuuki to give up on Roka would be the best idea. When Chie goes home to tell Yuuki this, however, Yuuki instead tells her about how Kasannoin "tainted" him. Because of this vague wording, Chie is led to believe that something sexual happened between them.

On her train home, Kotonoha witnesses the affair between Kasannoin and Hanon.

The next day, Chie tells Youka that Yuuki's staying home from school and asks her for advice on "boy love", to which Youka advises her to talk to their teammate Hatakeyama, who's really into that genre. Chie then confronts Kasannoin in their homeroom, but doesn't get a straight answer as to what happened.

Later, Kasannoin takes Kotonoha aside and swears her to secrecy concerning his affair with Hanon. Otome, who had seen this exchange alongside Roka, tells the latter about Kotonoha's reputation concerning boys and says that in a sense, she (Otome) and Roka are "kindred spirits".

Chie, having caught wind of Kotonoha's secret and thinking it might be key to understanding what happened to Yuuki, has Otome take Kotonoha to the team's locker room, where Chie prods Kotonoha to tell her the truth. Just as Kotonoha informs Chie and Otome about Hanon and Kasannoin, Nanami enters and accuses Kotonoha of lying. Upon hearing Kotonoha's description of Hanon, however, Otome admits that it might be true, having known Hanon since middle school. Nanami is in disbelief, while Chie is relieved that nothing really happened between Yuuki and Kasannoin.

The next day, Yuuki returns to school, where Kasannoin apologizes for the incident and swears Yuuki to secrecy concerning Hanon.

Meanwhile, Nanami blames Kotonoha for making Kasannoin cheat on her and goes to hit her, only to be stopped by Chie. Chie, who has come to the conclusion that Kotonoha is Yuuki's girlfriend, promises to protect her.
