The photo seems to have been taken after 2PM's 'Legend of 2PM' tour stop in Osaka, Japan. The group performed in Osaka from January 28th to the 30th, and it appears they had some free time during their stay in Osaka.�

Nichkhun can be seen squatting down next to a statue of a boy holding a giant ice cream cone, and is pretending to take a bite out of the huge ice cream. His mischievousness had fans chuckling when they saw the photo.

2PM will move onto Tokyo and Sapporo for their tour to showcase their trademark beastliness to the rest of Japan.
