Kwon Eun Bi and Jonathan Yiombi join as guests in today's The Perfect Code Race. Each Running Man member starts with seed money they get from a random QR code they scan at the start of the race. Eun Bi and Jonathan will have different tasks to earn their money. With that seed money, the members and the guests will scan QR codes in missions to make it grow. In the end, they race with QR codes on their backs with questions they must answer to eliminate the other to earn even more money to determine who faces the penalty. (thetvdb.com)
