Singer John Park offered f(x)'s Krystal a fist bump instead of a handshake.
On the first episode of Mnet's 'Enemy of Broadcasting', which aired on May 29, John Park made a visit to his senior musician Lee Juk's studio. When John Park saw Krystal talking with Lee Juk, he greeted politely.
When Krystal went for a handshake, John Park offered his fist as he was a bit shy, leaving Krystal bewildered. John Park explained, "In Korea, we need to be careful with physical interactions. It's because there is a saying, " A boy and a girl should not sit together after they have reached the age of seven"," making people laugh.
On the show, the special guests included Krystal, Kim Jin-Pyo, Baek Jin-Hee, Ryu Seung-Wan, Jin Joong-Kwon, and Nancy Lang.
