On March 17, Kwanghee enlisted in the military for his mandatory service. This means he's leaving broadcasts for about 2 years. This also means that 'Infinity Challenge' is again one member short. 

With this in mind, the talk about Noh Hong Chul coming back to the show resurfaced. Many netizens believe he's the ideal choice for the 6th member while some oppose the idea of having a ''criminal'' back on the show. Netizens are also recommending several other celebrities for the position such as Lee Kwang Soo, Super Junior's Heechul, Jun Hyun Moo, and former 'Infinity Challenge member Leessang's Gil.

At the press conference for new JTBC variety show 'Jobs' on March 28, Noh Hong Chul was asked about 'Infinity Challenge'. He opened up and said, "I think a lot about 'Infinity Challenge'. It's a show that I adore and support. I'm very cautious about returning to the show because I left after making a big mistake." (Noh Hong Chul left 'Infinity Challenge' after a drunk driving incident.)

He continued, "There will be some people who'll favor [my return] because I've worked for a long time with the members and have great chemistry, but I'm afraid that some might find that predictability old. I'm worried about the tough decision on whether it'll be right for me to go back if I can or to let a new person make it more fulfilling and energetic. I can't give a definite answer."

Park Myung Soo, a current 'Infinity Challenge' member who's appearing on 'Jobs' with Noh Hong Chul, commented, "Noh Hong Chul is like my brother whom I can open up to about personal things. I don't want to pressure him but he used to say that he'll not come back and now it's different. If given more time and if things work out, I think it'll be good to work together again."

Who do you think should join 'Infinity Challenge' as the 6th new member?
