Imagine the Korean version of New York. It's very busy and crowded and so many people, well in the city anyway. Tall buildings, cool cafes, lots of shopping places, lots of street vendors, no tax and great food :]
But there's bad pollution, and bad weather in summer and winter. It's extremely hot in summer and dark gray and super cold in winter, with rare snow. :<
But fall is beautiful

Oh and the people can be quite unfriendly.
Every thing's much more peaceful in the country side, however! And beautiful.
