Hiroki Tsutazawa, a second-year student who can't ignore people in need, has been curious about Kurumi Hiiragi, who sits next to him. If she was just a flashy-haired gal, he might have treated her as just another classmate. However, Kurumi, who had a bad reputation in the past, often gazes out the window with a sense of resignation, distancing herself from those around her, making her stand out in class.
Their relationship begins to change due to a certain coincidence. Hiroki learns about an unexpected side of Kurumi and starts to question the situation surrounding her. Kurumi, on the other hand, is moved by Hiroki's meddling nature and gradually becomes interested in him. This is a romance with a gal who, despite her looks, is actually pure and sensitive. It all starts with a teasing kiss and unfolds like a spring breeze.
