She clings to them with the hope that she will one day experience a love story of her own—one that will sweep her off her feet and make her heart flutter. However, reality is often disappointing. When a classmate from junior high confesses his feelings to her, Yuu finds that she feels nothing. Unable to give him an answer, she becomes convinced that she is unable to fall in love.
