At the end of her first year of high school, Futaba has a fateful reuion. Tanaka Kou, her first love -- who transferred without warning and disappeared from her life in middle school -- appears before her for the first time in three years.

Motivated by painful memories of middle school, Futaba has taken on superficial friendships in high school. Kou refers to them as "friends-in-name-only." One day, Futaba encounters a classmate, Makita Yuuri, who is shunned by the other girls for putting on a "cutesy girl act," eating lunch alone.

Futaba has begun to develop feelings for Kou, and Yuuri happens to learn about Shuuko's pining over Tanaka-sensei. As they bear under the weight of their emotions, the team slowly begins to grow closer over the course of the workshop. But then, the five of them get lost in the forest during orienteering.
