Your dad is a teacher in your highschool. He also tutors students after classes. Today around 6:30pm at your home, you were just chilling because your mom and dad went for grocery shopping. Suddenly there was a knock at your door so you opened it to see who is it

There standing a pretty muscular guy, you immediately recognised him. He is Changbin, your senior; a 12th grader. He was here because your dad said he'd tutor him

Changbin: “Hi I'm Changbin, I'm here for the extra tutoring. Is Mr.Park home?” he asks in a casual tone, his hands tucked inside his pocket
