At yesterday's successful concert held in Shanghai, 2PM's Nichkhun held the world premiere performance of his self-composed track, titled "Let It Rain".

Performing flawlessly on the piano, Nichkhun proved that he was more than a pretty face as he showcased his much-improved vocals with the sweet ballad-like English track. As a gift to 2PM's fans, the lyrics are meant as a salute to their never-ending devotion to each other.

Check out a fan-taken video of his performance below!
