Close friends Heechul and Son Dam Bi have a long and playful history together.

Super Junior member Heechul was the guest on the October 17th episode of MBC's 'Tutoring Different Generations' where the topic of his close friendship with Son Dam Bi was brought up.

Heechul revealed the story behind why he refers to Son Dam Bi as "my woman" and she calls him "my man."

"They are simple endearments we call each other all the time when we do not have significant others," he stated. "If I called her and said 'Dam Bi' [instead of 'my woman'], that means I have a girlfriend."
