Yali (Kang Hye-jung) lives with only a lizard for company, and she claims that she carries a spell on her body. She has been isolating herself until she meets her new deskmate, Jo Kang (Cho Seung-woo). This new classmate believes what she says and is willing to stay by her side. For some reason, Yali disappeared. The next time they met was in the second year of high school. Jo Kang found Yali in the name of studying. At this time, Yali was no longer wearing a yellow raincoat, and she had become a beautiful and generous girl. The time they spent together was very happy, but Yali disappeared again, and Jo Kang was sad again. During the days when Yali disappeared, Jo Kang became a bank clerk. He never gave up looking for Yali, but he hired a private detective and could not find Yali's whereabouts. One day, Yali's sudden appearance made Jo Kang very excited, but Yali came to say goodbye.
