Jinx manhwa

How far would you go to pay off a mountain of debt and save your dying grandmother when the only solution is a dangerous deal with a beast? In the sensational hit Jinx manhwa, physical therapist Kim Dan finds himself at the absolute rock bottom of his life, hunted by loan sharks and blacklisted from his profession. His luck seemingly changes when he is hired by the world-class MMA champion Joo Jaekyung, a man whose physical prowess is matched only by his ruthless personality. Jaekyung offers a life-changing five thousand dollars for a single night of “treatment,” claiming he suffers from a peculiar jinx that can only be broken through a very specific, intimate encounter before every big fight.
