In addition to attending, it has been reported that the 'Infinity Challenge' members donated to an organization for the Sewol relief effort and requested that the details of their donations may not be revealed to the public. Their agency reps stated, "The members quietly [donated] so we didn't know about it."

An insider also stated in an exclusive by No Cut News, "'Infinity Challenge's 'Yoo Jae Suk and HaHa and their 'Running Man' co-stars Lee Kwang Soo and Kim Jong Kook, who they're normally close friends with, visited the memorial together."

'Infinity Challenge' and 'Running Man' will not air this weekend in light of the Sewol tragedy.
