Yu-Yongng is a girl who has grown up alone in an old apartment since she was fourteen. One day, she discovers Si-An, an eight-year-old boy, sitting alone on the stairs as if he’d been abandoned. Unable to turn away from a child who resembles her, Yu-Young brings Si-An home, and the two become each other’s only family in the world. *“What do I have to do to marry you, big sister?” “You just have to grow up, get into Harvard as valedictorian, and graduate as valedictorian too.”* It was just a joke she made to a little boy. It was definitely just a joke. (Source: Naver, translated)
