Sixteen-year-old Haerin lives quietly in Busan, withdrawn and uncomfortable with people, carrying questions her mother refuses to answer-especially about her absent father. While helping prepare for a yard sale, Haerin finds a locked box containing old photos from her mother's high school years. One photo shows a girl who looks exactly like Haerin. The girl disappeared long ago, and her mother won't explain why.
The next morning, Haerin wakes up in early-2000s Busan, living a life that feels unfamiliar yet instinctive. At a new school, she's drawn into a close-knit group of girls from the photo, including Danielle, a warm, curly-haired girl whose attention slowly breaks through Haerin's guarded walls.
As Haerin navigates the past, she sees a different version of her mother, uncovers buried secrets, and forms a slow, fragile bond with Danielle. Caught between timelines, Haerin must face who she is, why she's there, and what it means to belong-knowing that loving the past may come at the cost of her future.
