On January 11, 2PM's Jun.K appeared as a guest on radio show 'Choi Hwa Jung's Power Time' in order to promote his comeback with '77-1X3-00'.
He also revealed that he will not be doing any promotional activities for this album, as it is solely a gift to fans before his enlistment this year. He also revealed a song from his album, "Alive Part 2", for the first time ever on the radio broadcast.
About his enlistment, Jun.K said, "After 2PM's solo concert, some of the other members and I need to fulfill our mandatory military service duties, so we will have to separated from our fans for a bit. We are preparing handwritten letters for our fans... We haven't decided exactly how we'll deliver the handwritten letters. But we're preparing them diligently."
2PM will be meeting up with fans at their last domestic solo concerts before Taecyeon and Jun.K's enlistment toward the end of February and into March.
