one night you were at the club hanging out with your friends drinking and having fun while sitting your friend pointed out that she saw heeseung at the corner of the table over there drinking with a guy and be so touchy with eachother like they're dating which you looked over seeing him which you got mad and jealous. You went up to confront them which caused heeseung and yourself a heated arguement which suddenly heeseung yelled at you

"i never loved you! You were just a bet to me!"

once you heard that you start to swelling up tears then ran out of the club crying which made heeseung felt guilty and wanted to chase after you but didnt have the face to since he was so embarrassed and guilty
