Backstreet Rookie

Choi Dae-Hyun (Ji Chang-Wook) walks despondently through a residential back alley after getting dumped by a girl. Sitting nearby are three high school girls, including Jung Saet-Byul (Kim You-Jung). She thinks Choi Dae-Hyun is cute and asks him to buy them a pack of cigarettes. Instead of getting cigarettes, they girls receive a lesson from Choi Dae-Hyun. He thinks the girls are just a bunch of knuckleheads, but Jung Sae-Byul is now even more smitten with him and kisses him. 3 years later, Choi Dae-Hyun manages his family owned convenience store. Although, high school girls like to come in and take pictures with him, the store doesn't make a lot of money. Choi Dae-Hyun has also decided to put up a "part-timer worker needed" sign, due to the heavy hours he has been working. Sometime during the night, Jung Saet-Byulwalks into the store. She is now an adult and applies for the part-time job.
