Summary:

Dan Kim, a physical therapist, has faced a string of misfortunes for as long as he can remember. With a sick grandmother, threatening loan sharks, and a former boss making it nearly impossible to find work, Dan is running out of options. So, when he finally gets hired to treat top MMA fighter Jaekyung Joo, it feels like a dream come true. Jaekyung offers him a tempting $5,000 for a treatment the night before a match, claiming he has a “jinx” that requires a special kind of care. However, Dan isn’t quite ready for what Jaekyung has in mind. While Jaekyung is a fierce competitor in the ring, he’s even more intense in private, and Dan worries he might not be able to handle him at his most primal. Still, the lure of much-needed cash leads Dan to accept this risky proposition. Could their night together be the key to breaking Jaekyung’s jinx once and for all?
