Sakaki shows pictures of Hana and Shinichi napping together on campus to Ami. The four of them then go clothes shopping, and Hana shares with Ami that she has been going swimming with Shinichi, who complimented her on her bathing suit. Later, they play futsal and meet acquaintances of Sakaki, who challenge him to a game. On another day, Hana daydreams she is Shinichi's upperclassman while they head to her house. After Tsuki taught Shinichi how to make udon, he became good at it but Hana gives him harsh criticism. While Shinichi practices properly cutting the noodles, Tsuki still misinterprets his motivations, and a conversation with Hana only makes the misunderstanding worse. That evening, Hana's younger brother, Kiri, eagerly eats the udon prepared by Hana's senpai, who he erroneously believes is a woman.

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.
