There are lots of great and popular singers in Korea. I think they are great people. They practice songs all day and night. And singer who dance, they have to memorize all the movements and the patterns to perform. Also even other people, like stylish, dance maker and directer work hard together to make singers song more nice and valuable. So I admire all the people who work for the K-POP entertainment. Thank You for All the Singers and Staffs. :)
