As the sun sets on a quiet afternoon, a young girl with glasses finds herself caught in a moment of intense intimacy with a boy named Yuyu-kun. What begins as a tender, sleepy encounter in bed quickly shifts into a surprising exploration of physical sensation and growing desire. While she wonders if her feelings for another boy named Nageshi-kun will complicate things, she finds herself unable to resist the clumsy yet determined advances of Yuyu-kun. Amidst secret touches and whispered desires, the tension between youthful innocence and newfound physical pleasure creates a heady, unpredictable atmosphere.
