On the day of his high school graduation, when white snow fell like his name, Baek Seol, who had secretly loved his junior Yu O-Geon, tried to confess his feelings one last time but met a tragic end. But years later, when they reunite by chance, O-Geon approaches him actively, unlike in the past. Baek Seol finds himself shaken once more by the feelings of his first love, which he had carefully tucked away...
