Group 2PM's member Nichkhun seemed shocked at Yoo Jae Suk's direct question about Tiffany.

In SBS entertainment program "Running Man" aired today, Nichkhun was asked about Tiffany.

Yoo Jae Suk said to Nichkhun, "I'm glad you were doing well in Thailand. I'm glad you're personally doing well too," referring to his relationship with Girls' Generation's member Tiffany.

Nichkhun seemed shocked but said, "I'm happy." Yoo Jae Suk then asked, "What is she doing right now?" Nichkhun thought he was talking about Taecyeon so he said he is filming for a drama.

But Yoo Jae Suk said, "Tiffany. Tiffany. What's Tiffany doing right now." Nichkhun answered, "She's resting. She's sleeping." Then Yoo Jae Suk once again said, "You guys talked this morning," arousing laughter.

Internet users who saw this commented, "Nichkhun seemed shocked at the question," "They seem to be doing well," etc.
