I walk around a lot secretly. Even when I use a car, I park it briefly and walk. It seems that I still need some time alone to think and sort out things myself.

No matter what I face, I must have a mindset that 'it must go this way.' Although it gets to the point where I can't joke around for fun, I'm working hard right now, which is why I think I can look at matters through an objective point of view.

I remember the time when I met my first girlfriend. It was raining and I was walking, and all of a sudden this girl put an umbrella over my head. Then my hair and clothes were wet, and she said, “Oh! There's something on your shirt.” And that was when I just fell for her.

Even when you're feeling dejected, don't avoid the problem, confront it. That way you'll eventually realize that your dreams are in fact attainable.

I hope that the members of TVXQ would always continue. Right now, our friendship is already very strong. But I hope that in the future, it will definitely grow even stronger!

I'm usually quite honest about expressing what I feel but there are times when I let things pile up inside me and the hurt feelings take over.

I get so much energy to work harder when I meet and greet younger kids because they like me with such innocent hearts.
