Yoochun showed the two sides of him as an actor on set, who is approachable and diligently studies his script, and the actor onscreen who is full of charisma.

He shared how much fun he is having while filming 'Three Days', "It's really going well. It suits me and I'm having fun. Although it's difficult because it's always cold and there are many action [scenes] during filming, because of those things, I think I am changing a bit. I tried to be as polite as possible in the past but now I am really comfortable and joke around with the staff in a friendly way without hesitation."

The JYJ member also shared what he learned from filming 'Sea Fog' and 'Three Days' simultaneously,�"As I film my movie, I thought that consciously trying to be polite can also be uncomfortable. It would be better if I approached others comfortably first. As I ate and drank with the staff every day for four months, I learned a lot."
