MBC's 'Radio Star' featured two SM artists as guests on May 4: Kangin and Dana!

On this day, Kangin relayed, "Dana is stronger than I am.  There are only two women I'm scared of in our company and they are BoA and Dana."  It was mentioned that the two debuted before him.

Hearing this, Dana in with, "That's irrelevant.  It's not important who debuted first. SM does not have a structure in which the successful juniors are uncomfortable around the seniors," raising eyebrows.
