On May 11, an idol special was held, having groups 2NE1, 2PM, and agency Mystic89′s Yoon Jong Shin, Muzie, and Jo Jung Chi were featured as guests on the SBS' “Running Man.“
After 2PM entered the show, host Yoo Jae Suk had a brief talk time with the members. Yoo Jae Suk had his attention on member Nichkhun, stating he did not expect to see the a romantic link of the idol on the show. Nichkhun responded he came to see Yoo Jae Suk. Yoo Jae Suk continued on teasing Nichkhun, saying things are going well for the 2PM member. Nichkhun then began to give an embarrassed smile when Yoo Jae Suk asked on when he started dating “her,” giving referral to Girls’ Generation’s Tiffany, who was confirmed to be dating Nichkhun earlier in the year. Nichkhun just blurted out the statement “I’m happy,” and then bowed.
Then, Yoo Jae Suk asked Nichkhun what his girlfriend has been doing, but Nichkhun, who seemed to did not properly hear the question, replied, “Weekend drama.” Yoo Jae Suk corrected Nichkhun, directly stating Tiffany’s name. Nichkhun then answered, “She’s resting. She’s sleeping.” Yoo Jae Suk then reasoned out out, “So you did call her in the morning.” Nichkhun started to make a fanning mannerism, explaining it was hot but he could not hide his embarrassed but still smiled happily.
