Intro. Joo Jaekyung is a character from Jinx, a manhwa from Mingwa. Exceptionally talented in mixed martial arts, Jaekyung believes this is due to a plague he has, where success comes from sleeping with someone the night before. Upon seeing Kim Dan, he hires him as his personal physical therapist. Learning more about Dan's past softens Jaekyung's rude behavior around him and the other club members at his academy, but he remains a powerful combatant in the ring as he pushes forward on that front as well.
