Yuzuru is enjoying summer vacation with Ai and Kaoru, when Sousuke invites them all to join a band for the culture festival. Despite having no experience, Yuzuru winds up playing drums. He's hesitant at first, but it seems Sousuke is up to more than just making memories—he wants to convince Risa to pay bass, an offer which she curtly refuses. Risa's past, Sousuke's feelings, and everyone's musical challenges weave a complicated melody as yet another regret comes to light. Is it possible to communicate with someone who refuses to engage?

Yuzuru has begun to mend things with his ex-girlfriend Ai, finally overcoming his long-held regret. But his relief proves short-lived when fellow literature club member Kaoru stops coming to school. Yuzuru, who cares for her and knows something about her situation, tries his best to help, but she refuses him at every turn. As loneliness and a new regret take root in Kaoru's heart, how will her relationship with Yuzuru change?

Yuzuru Amida is filled with regret. Although he fell in love with free-spirited Ai Mizuno in middle school, he never managed to tell her how he felt and subsequently drifted apart from her.

As this pair of total opposites gets reacquainted, however, they sometimes butt heads and find themselves at odds with each other. When all is said and done, will they end up as friends...or something more?
