Super Junior's member Kim Heechul and singer Son Dam Bi showed off their friendship.

In KBS2 entertainment program "The Human Condition" aired today, group 2PM's Taecyeon and Super Junior's Kim Heechul came out as guests.

While driving in a car, Kim Heechul was asked, "Aren't you close to Son Dam Bi?" and was asked to call her.

After talking on the phone, Kim Heechul said, "If I call someone 'my girl,' that means I don't have feelings for that person in a romantic way," revealing that it's a nickname he gives to people he's close to.
