Oh Sung Gil, a new comic artist, is struggling with coming up with ideas for a new work. He takes a walk in the park daily to cool his head. But the real reason for walks the park is to look at a woman jogging in the same course every day (even though he has a girlfriend). One day, he gets a chance to talk to her, after just looked at her for two months. Sung Gil then follows her to the mountain where he gets lost. Suddenly, a strange man appears in front of him and the situation goes in unexpected direction.
