With Yui now living alone in her own apartment, she invites the others over for lunch. After Akari and Chitose leaves, Kyōko decides to spend the night only to remember she hasn't finished her homework.

With Christmas coming up, Kyōko holds a lottery to arrange the girls into pretend couples for mock dates. Kyōko and Chinatsu go to the movies and the arcade, Akari and Chitose visit some cafés, Himawari and Sakurako go to a restaurant while Ayano and Yui just sit around talking about their friends. Later, the girl's spend New Year's at home where they check their greetings cards from each other.

Kyoko and Yui, along with Ayano and Chitose, go on a school trip to Kyoto, where they explore the town, have a bath together and engage in a pillow fight.

Akari, Chinatsu, Sakurako and Himawari try to think of ways to pass time in class. Later, Himawari agrees to help teach Chinatsu to knit a scarf, which leaves Sakurako feeling lonely without her. As Valentine's Day comes and the girls give each other chocolates, Himawari gives Sakurako some Valentine gifts.

As Kyoko asks the others to help finish her doujin for a deadline, they are reluctant to let Chinatsu assist in anything artistic. Later around Christmas time, everyone goes to a karaoke place, where Chinatsu fails to get a duet with Yui. As a consolation, Yui takes Chinatsu to the movies, where Chinatsu's plan to cling onto Yui during a scary movie backfires.

As the second years are going on a school trip to Kyoto which brings up all sorts of déjà vu, Sakurako decides to go on her own 'trip' with Himawari, only to wind up getting lost. Meanwhile, Akari tries to cheer up Chinatsu as she becomes depressed over missing Yui and winds up in another dangerous situation. Later, as Himawari visits Sakurako's house, Nadeshiko recalls how the two used to be much closer in their childhood.
