Suho may well have been the guest on the February 24 airing of 'Radio Star' instead of Chen. However, Kim Gu Ra was vehemently against bringing Suho on the show. 

Kyuhyun had explained, "After receiving an invitation from 'Radio Star,' the company was wondering who to send and they were going to send Suho but switched to Chen the last minute. Kim Gu Ra was against [Suho coming on the program]."

Kim Gu Ra gave the reason for rejecting Suho, saying, "Even the company acknowledged that he's not funny." Yoon Jong Shin added, "Kim Gu Ra forcefully told the producer himself that Suho isn't funny."
