A young woman named Yuki suffers from a rare form of progressive amnesia that erases her long-term memories each time she sleeps. Determined to hold onto her identity, she keeps a detailed diary and records daily video logs. One morning, she wakes to find a note in her own handwriting that simply says, Do you remember me? and a photograph of a man she does not recognize. The note urges her to find him at a specific park bench that afternoon. There she meets Haruto, a quiet, weary-looking artist who claims they were childhood friends and that he has been searching for her for years. He shows her sketches of places and moments she cannot recall, yet each drawing stirs an inexplicable ache in her chest. As Yuki pieces together fragments from her diary, she discovers that Haruto was her first love, but a tragic accident on the night of their high school graduation caused her memory loss and drove them apart. The central conflict arises from her daily reset: each morning she forgets Haruto, so he must reintroduce himself and their shared past, while she must choose whether to trust him again. The setting shifts between her cluttered apartment filled with sticky-note reminders and the nostalgic seaside town where they grew up, with frequent flashbacks to their school years, a summer festival, and the cliffside road where the accident occurred. The narrative unfolds in two simultaneous arcs: Yuki’s present-day struggle to document and verify Haruto’s story before her memory fades, and Haruto’s hidden burden of carrying decades of grief and guilt, as he was the driver that night. Over repeated cycles of introduction and parting, Yuki begins to notice inconsistencies in Haruto’s accounts and in her own diary entries, suggesting that someone has been altering her records. A middle arc reveals that a mutual friend, Rina, who was also in the car that night, has been manipulating Yuki’s environment to keep her from remembering the full truth: the accident was not an accident but a deliberate swerve to protect Yuki from an oncoming truck, and Haruto took the blame to shield Rina, who was actually at the wheel. As Yuki’s condition inexplicably begins to stabilize, allowing memories to last for several days at a time, she confronts Haruto about the lies. In the final arc, they return to the cliffside on the anniversary of the crash, where Yuki experiences a violent flashback that restores her memory entirely. She remembers not only Haruto’s love but also her own promise to meet him again if she ever forgot. The story concludes with Yuki waking one morning, her memory intact for the first time in years, and turning to find Haruto asleep beside her. She whispers his name, and he wakes to her smile, finally certain that she remembers him. The narrative closes on her closing her diary with a final entry that reads, I remember everything, especially you.
