Seo Inguk is not a star who has a normal background. His family didn’t have enough money, and when he came to Seoul to become a singer, he had to live in a small room which is infested with rats. And you know, he reversed his life by becoming the winner of “Super Star K.” Because of such a background, he never acts haughtily even after becoming a popular star. He still acts like an ordinary person and is friendly to everyone. And he is a very sincere interviewee too.
