When six of the nation's top picks for K-drama villains appeared on this week's episode of 'Running Man', the stage was set for a perfect mashup of action and drama! 

Featuring Lee Yu Ri, Choi Yeo Jin, Seo Woo, Yoo In Young and Kim Min Seo, this is one episode you shouldn't miss.

With twelve people paired up into six teams, it was revealed that one of the couples was the heir to a massive fortune. The winners of each mini-game would be told a hint toward the true identity of the heir, along with a chance to switch the couples around.

Finally, with the real chaebol's nametag hidden somewhere inside the building at the final location, the goal was to stand together on a podium with his nametag affixed to their backs. A thrilling nametag-finding-and-ripping chase ensued, but the winner turned out to be Yoo Jae Suk and Kim Min Seo, who figured out that the true heir was Ji Suk Jin - and beat the others to the punch in a spectacular passion!
