It's the first day of summer. Chizuru decides on inviting some of his friends to go out, but ended up being rejected. Shun decides to invite everyone to the summer festival.

Chizuru, Kaname, Yuuki and Shun saw an unexpected confession of a quiet and shy girl to Yuuta. Even so, Yuuta does not tell any information regarding the incident to his friends. This results to the gang stalking Yuuta behind his back while he was on a supposed 'date' with her. In the end, it is revealed that Yuuta had known about the girl's situation all along; being bullied by her friends and wants to help her, even if it meant accepting her confession. The relationship between Yuuta and the girl, Takahashi-san is still unclear. However, at the end she and Yuuta broke up.

It's finally the day of the Cultural Festival and everyone prepares for their respective groups. Shun's class are doing a "cafe with a twist" and Kaname's class are doing a "stereotypical haunted house". In Masaki's class, they are going to play Cinderella on stage. Even if her role is a mouse, she is desperate to practice her dialogue. The gang watches her performance however, some of them are still wearing their costumes, which made Masaki to notice them easily, got nervous and accidentally mixed her lines up. Chizuru goes to comfort her after her performance.

On Christmas Eve the gang runs into Azuma-sensei and his childhood friend, Akira. While trying to help a little girl Chizuru accidentally knocks over a Christmas tree forcing all of them to dress up and work with Akira as Santa Claus.
