"We slept together in our underwear when we first met". Actor Ji Sung spoke of his first meeting with his good friend, JYJ's Jaejoong. During an interview with Starnews on July 21st, Ji Sung spoke out about his relationship with the superstar. Ji Sung is co-starring with Jaejoong in the upcoming SBS drama, 'Protect the Boss'. He began, "We went to MT (Membership Training) with all of the staff and actors/actresses before we began shooting for the drama... I first met Jaejoong there. After dinner and some drinks, I was trying to fall asleep, but Jaejoong came in the room and we had to use the room together". He continued, "There was only one King-size bed in the room. Neither of us really wanted to sleep on the floor, so we chose to sleep on the bed together. But the temperature in the room was so hot that both of us slept in our underwear without any words said. Guys bond quickly after they go to the public bath together, and I guess it's kind of the same sort of situation" (laughing).

Ji Sung didn't save any words praising Jaejoong's acting passion either. Ji Sung commented, "Jaejoong has already become a top star as a musician, but he takes acting as his first step and portrays his maknae role at the filming set very well... He analyzes his character very thoroughly before coming to the set. He shows a great sense of professionalism and responsibility". Adding on, "Because Jaejoong shows so much effort, many of the senior actors, including me, put in our efforts to make his adjustment to the acting scene a bit smoother. Jaejoong answers back to our efforts with an adorable attitude. I hope he will have a smooth future as an actor", sharing his sentiments. 'Protect the Boss' will premiere on August 3rd as a follow-up to "City Hunter". Source: Star News via Nate
