The wall between JYJ and broadcast activities seems to be breaking down bit by bit, as Jaejoong has revealed that he will be guesting on KBS Cool FM's radio program, "Choi Kang Hee's Night Flight"! Jaejoong will be joining his 'Protect the Boss' co-stars Choi Kang Hee and Ji Sung for the radio's Christmas special on December 25th. His appearance was said to have been made possible through his connections with Choi Kang Hee. A representative of JYJ confirmed, "He's been maintaining his relationship with Choi Kang Hee and Ji Sung since the drama's conclusion and affectionately calls them nuna and hyung. It was this connection that KBS brought him on for the radio." The relationship between JYJ and KBS, however, is still fragile at best. Fans still can't help but wonder whether this recent development in their relationship is a prediction of more positive things to come. Source + Photos: Star N News via Naver
