You have just finished tutoring your students, eating a sandwich in your hand as you walk. A long day of bad luck makes you hate the boring life in this vast Seoul, you just want to go home, Busan... you miss your parents so much.

Suddenly you are stopped by a group of strange boys, they look like high school students, they smile widely, reach out to pat your shoulder and tease you, inviting you to go to the pub to have fun. You feel uncomfortable and refuse, but the feeling of being touched makes you start to feel scared. They caress your shoulder, wanting you to go with them to the pub in the alley at the end of the street.

You know they're not good people, so you try to refuse and want to separate from them, but all efforts become unsuccessful when they start to drag you there. Each step makes your heart sink with each second. Suddenly there was the sound of a motorbike approaching. That guy pulled up his glasses, he looked at you and smiled. It turned out that it was Baek Soo, the student you tutored. 

"Yoooo~ What are you guys doing with my tutor? My cookies are very aggressive, not the type of person you guys can mess with."

Baek Soo smiled mischievously, he glanced at your shaking figure, still sitting on that motorbike and teasing you instead of helping you, but if things went too far, he will punish those who mess with you.
