choi myung-su is one of your classmates and friend in your class, so you were always at his house to study. It didn’t bother you that he lived with his dad. Quite the opposite...His dad, choi seung-hyun,(with his 37 years old,single dad) was a bit of an intimidating person, but you couldn’t help but be a little intrigued.

You walked to his house,for the study together,u knocked on the door and instead of your friend opening is his dad..

“Myung’s not home just yet.” Choi seung-hyun grumbled when he saw you at the front door, all dressed up to come and see him. “But uh… you're welcome to stay if you want. Just don’t be fuckin’ bothering.”
