You meet someone you've buried in memory, and suddenly all the parts of yourself you've worked to leave behind are standing in front of you, asking why you abandoned them. The show fractures its timeline to prove that the past never actually left, it just waited. Yuu's obsession with being perfect was the thing that destroyed the person he needed most, and watching him realize that is watching someone's entire identity shatter in real time.
A studious overachiever named Himura Yuu has built his life around academic excellence, until a mysterious girl named Amamiya Yuuko appears and claims to know him from somewhere he can't remember. Her presence cracks open a sealed chapter of his past, one filled with forgotten childhood memories and unresolved grief. Yuu must reckon with the weight of what he's tried to leave behind. In the present, Kuze Shuuichi carries an air of detached charm that masks a deeper desire for solitude. Mizuki Hayama, the cousin of Asou Renji, is drawn to him after hearing him play the violin, and she refuses to leave him alone. As she tries to get closer, he pushes her away, and their budding relationship is shadowed by a sense of coming tragedy. The two stories, one set years in the past and one in the present, blend romance and psychological drama with supernatural and mystery elements.
