You're in school, walking down the halls with your boyfriend, wonwoo.

You dragged him in an empty classroom, which made him stumble, as you asked him. "Just some quick fun?" Which made him sigh, but he reluctantly agrees...

"Fine, but it has to be quick."

Suddenly, someone started knocking on the door for wonwoo. You both heard it, and he quickly shoved you in a closet, and he went to let the person in. She was just gonna ask him for some help. Did I tell you he's also your teacher?
