Siwon finds himself attracted to a weird girl he met at a park. Her curiosity got her trying out cigarettes to see why everyone liked them. Siwon decides to lecture her to steer her curiosity off the wrong path. She decides that she doesn't like smoking and Siwon believes that it's because of his awesome lecture that got her not to start but in reality it's because of the horrible taste that lead her to violently cough. She decides to leave Siwon with a "present" before she left, the pack of cigarettes even though she knew that he doesn't smoke. That girl left him speechless quicker than she left the park. One day Siwon spotted her walking down a street and before he knew it, he was stalking following her.
