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.

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.
