On the January 31st episode of "Paradise Ranch," TVXQ's Changmin and Joo Sang Wook's characters strip down to win their lady love. After a coincidental meeting at a resort pool, Changmin and Joo Sang Wook, who are both tied to love interest Lee Yeon Hee, will flex their abs and hit the swim lanes in what quickly escalates into a battle of egos. With Changmin slowly realizing that he still has feelings for his ex-wife, Joo Sang Wook quickly answers his challenge - it's sink or swim for love, and round 1 of this clash will be quite the spectacle. Though we have to wait until the episode airs to see who the winner will be, the teaser pictures alone are just enough to make any fan girl's head swim.
