Maria, who had lost her mother when she was young, is spending her days swamped with studying for college entrance exams and working at her part-time job. She is envious of her bright happy-go-lucky schoolmates, making her feel lonesome. During that time, a suspicious man she meets at the park asks her, “Don’t you wish… there were two of you?” Maria thinks, “If there were, would I have more freedom than now?” As if to grasp at straws, Maria takes the man’s hand, and then her memory fades off. Once she wakes up, there’s a girl identical to Maria lying on the floor in front of her eyes!
