Most of the job on DDP was already done by the time I became mayor. So was Gwanghwamun Square, described by many architects as the city's worst architectural creation, and the new city hall. I did not think that redoing them would be the right approach as that would only create new problems.

I published a thesis about animal rights when I was studying in England in 1991.

Being elected as Seoul Mayor came to me like God's calling.

As the nation is aware, I have been doing charity movements through the Beautiful Foundation and Beautiful Stores, and carrying out projects to promote hope and governance of our society.

Many homosexual couples in Korea are already together. They are not legally accepted yet, but I believe the Korean Constitution allows it. We are guaranteed the right to the pursuit of happiness. Of course, there may be different interpretations to what that pursuit means.
