Shun is now a Second year High School student, together with his childhood friends Yūta, Yūki, and Kaname. During their break at the rooftop, Kaname wants Yūki to join a club, but turns out to be a bit difficult for them to find him one.

Shun, waiting for his friends to eat lunch together finds a girl with a scraped knee. He attempted to confront her, but she ran away. While the girl was stunned at the hallway, Shun succeeded in chasing her, and gives her a bandage. The next day, Shun finds a letter that states that he will get cursed.

Yuuki has been asked by a first year student named Ryunosuke Matsushita, who is a member of the Manga Society of their school to draw a five-page manga for the club's anthology. After accepting this, Yuuki decides to divide his work with his friends namely: Yuuta working on the first page, Yuuki on second, Shun on third, Chizuru on fourth and Kaname on the last page. When they were all finished with their work, Chizuru asked Yuuki to make copies for everyone. Yuuki attempted to shred it to bits but was stopped by Chizuru and Kaname. On the side story of the episode, it reveals that Ryunosuke Matsushita admires Yuuki and thinks of him as his "hero".

After class, Shun gets an incoming call from his little brother, Fuyuki stating that they accidentally got their English notebooks mixed up and wants him to give it to him as soon as he can. The gang decided to visit his school, which is also where they (minus Chizuru) attended their Middle School.

Shun proposes to the rest of the gang to conduct a work experience at their old school, Hidamari Kindergarten. Almost everyone were excited except for a pouting Chizuru who attended a different kindergarten. Shun cheers the gloomy Chizuru up and they went on to their plan. Once they arrived, they end to up see some quirky pupils around and a certain pupil who is a bit troublesome especially for Kaname. The episode ends with Shun exposing Kaname's feelings for his past teacher, Kaori-sensei, thus making Chizuru laugh and embarrassing Kaname.

The gang goes over to Kaname's house to deliver tangerines and much to Kaname's chagrin they stay for dinner and invite themselves to sleepover. Hijinks ensue as they reminisce about the past and joke about each other's idiosyncrasies.

On New Year's Eve, the Asaba twins have a fight.

Shun worries about how fast his little brother's relationship is progressing - he thinks kissing is too early for middle schoolers. He calls over the gang to discuss the "emergency" which only worsens his anxieties. As a result the gang spies on his hormonal brother's date, and hilarity ensues.

As the gang's third year begin, the sport festival is on the way.

Shun is troubled about his future as everyone else seems to be more prepared than him. Also, Chizuru, Yukki, and Kaname visit the Tea club with Shun and Yuta.
