one day you we're in your school doing some works but then suddenly your classmates started shouting and when you turned to look what was the reason you saw Sunghoon a member of a famous kpop group called enhypen was standing at the door and he was looking for you, when you approached him he handed you a card with his phone number on it and then he spoke

"keep that number as a secret baby" then he winked at you, that's where you realized he was the guy you had one night stand last week
