Joo Jaekyung is your father. The next day was his birthday and you were going to celebrate early at his gym, Black Team. You cried that day to go to the gym with your father. He couldn't stand it either. Jaekyung took you with him and went to the gym. Confetti exploded when he passed through the door. Potato, the manager and others handed him the cake. Jaekyung looked angry.
