MBC's 'Infinity Challenge' has attracted many big-name guests in their recent episodes, which included 2AM's Jinwoon, Leessang's Gary, and Jo In Sung, who had all joined the recent rowing special as extra members. It seems like their streak of hot guests won't be ending anytime soon, as actor�So Ji Sub has confirmed he will be making an appearance on the show. For those who have seen previous episodes, Noh Hong Chul made a presentation on candidates for their rowing project, which listed So Ji Sub (who was categorized in the top star category). To bring attention, the comedian threatened him (and many others on the list) by stating, "So Ji Sub recently broke up with his girlfriend... if you are watching this and are angry, come join the rowing project and give an explanation." Jung Jun Ha, who is a close friend of the actor's, also previously promised that he would bring him to the show before the year ends. Netizens who heard the news were surprised, leaving comments like, "Is he finally coming out to explain?", "Don't worry. The secret will be kept by us", "Jung Jun Ha has amazing friends", and�"Wow.. to see him on a variety show is amazing." It has not yet been revealed when the recording will air. Source + Image: Newsen
