Choi Dae-Hyun (Ji Chang-Wook) runs into a group of female high school students, including Jung Saet-Byul (Kim You-Jung). The girls look like troublemakers. Jung Saet-Byul asks Choi Dae-Hyun to do an errand for them, which is to buy cigarettes from a convenience store. Choi Dae-Hyun buys the cigarettes for them and Jung Saet-Byul gets his cellphone number, but he never gets a call from her. 4 years later, Choi Dae-Hyun is now 33 years old. He runs a small convenience store after he quit his job at a large company. He is looking for a part-time worker to work the night shift at his convenience store. Jung Saet-Byul comes to his store and she soon starts to work there. She is not a troublemaker anymore. Jung Saet-Byul is now a university student and guided by her strong morals.
