During his interview with Xports News at a cafe in Shinsadong, Seoul on the 30th, Jaejoong proved that there's no bad blood between him and TVXQ, showing his support by saying, "I hope [Yunho] does well."
When asked if he heard about Yunho's mention of him during the press conference for MBC's 'The Night Watchman', Jaejoong shared, "I saw that article... I think he will show good acting... To be honest, I'm not in a position to tell someone to do well... All actors go through a growth process. Even veteran actors, who act well, face a dilemma at one point or another, so compared to those veteran actors, we still have a long way to go."
"Since Yunho also went through a growth process, I believe that he will show even better acting this time around. Among the staff and actors whom I worked with for this production, there are some who have worked with Yunho. They tell me that he works really hard. Actors who work hard are bound to succeed."
[Update] - According to another media outlet MBN, Jaejoong also expressed his concern for Yunho, who has a tendency to focus on work too much and forget to stay hydrated. When asked if he had any words for Yunho, Jaejoong said, "It'll be very difficult for him as it's his first historical drama. I know because I've done it before. Since it's also hot and such related factors, he'll probably receive a lot of stress too... For what I want to say the most to him, it'd be that I hope he drinks a lot of water as he films. When we promoted together, there was a time when he got dehydrated, so I hope when he films this time he drinks a lot of water and takes care of his physical condition... Yunho is the style that works really hard at whatever it is he's doing. I hope that he looks after his condition as he works instead of rashly working so hard in fear that people will speak badly of him... I also hope that his first attempt at a historical drama will turn out well."
He also directly addressed Yunho with a message, "Yunho-yah, are you doing well? I'm doing well... It's probably your first historical drama, and it's going to be very difficult. I guess there will be a lot of outdoor filming too. With the lack of time, there will be a lot of CG work and martial arts practice. So it'll be very tiring physically and it'll probably be really hot, so drink a lot of water as you practice. It's good to work hard, but make sure you think about your body too."
