Dark but Pure?

Kim Min-hee is a third-year middle school student whose ordinary life takes an unexpected turn after the summer break. During the sweltering vacation, her classmate Saeha spent his time outdoors and returned with deeply tanned skin, looking entirely different from before. Despite his darkened complexion, there is something about him that continues to captivate Min-hee, leaving her unable to tear her gaze away whenever he is near. As the intense heat of summer lingers into the start of their final semester, Min-hee finds herself increasingly distracted by Saeha's presence. The familiar routines of their classroom now feel charged with new emotions she never anticipated. With only one semester left in middle school, she begins to wonder if the days ahead can truly remain as simple and unchanged as they once were, or if this lingering summer warmth will alter everything between them.
