Ending the concert successfully, Kim Heechul wanted nothing more than to rest, especially since he felt that his foot started to hurt a bit. However, fate has other plans when it mocked them right on their faces. Spotting a strange woman, he simply wanted to know what she's there for before inevitably calling the security to her out.

Who will confess first?
