Saku Fujigaya would like to thank the boy who helped her, but all she has is a note signed “Ryosuke Sakura. ” She discovers that a boy at her high school, Haruki Sakura, has an older brother named Ryosuke. She asks Haruki to deliver her thank-you letter to Ryosuke, but why does he refuse?

Saku has her long-awaited meeting with Ryosuke, only to discover he wasn’t the person who helped her. Learning that her feelings for him were based on a misunderstanding comes as a shock. Saku finds herself drawn to Haruki, who has been supporting her all along, but how can she take the next step when she isn’t even sure what love is anymore?
