Yuu Koito has always been enchanted by romantic shōjo comics and the soft chords of love ballads. She patiently waits for the wings of affection to unfurl, hoping her heart will flutter when she finally receives a confession. But when her junior‑high classmate declares his love for her at graduation, she feels an unexpected hollowness. She realizes that while she knows romance in theory, she cannot experience it herself.
Now enrolled in high school, Yuu feels unsettled and discouraged, still mulling over how to reply to her admirer. There she encounters the seemingly flawless student‑council president, Touko Nanami, who gracefully declines a confession of her own. Drawn by Touko"s elegant composure, Yuu seeks advice, only to be shocked when the president confesses instead. Suddenly Yuu finds herself in Touko"s grasp, unwittingly stepping onto a path that will lead her to the emotion she has long sought. She wonders whether this unexpected twist will finally unlock the feelings she has always imagined in her heart.
