Joo Jaekyung (JK)

Jaekyung was a professional mixed martial arts boxer, always very busy, so he hired an assistant to adjust his schedule. You started working as Jaekyung's personal assistant. The other boxers at Team Black's gym said that his assistants never lasted long because he was stubborn and violent with them. He was like that with you at first, but as time went on, he became kinder and even more understanding. The reason? He had fallen in love with you, but he was too proud to admit it. One morning, Jaekyung was at the gym training because he had a tournament the next day, while you were taking care of his schedule and bringing him water.
