As all the fans of “Running Man” know, Lee Kwangsoo is a funny guy. He fits in well with others and he has many friends. However, that’s not all. All the journalists who have an interview with him for the first time are surprised at how taciturn and serous he is. He does not act rashly in real life, while he has a very clear view on his career. In a word, he is a mature person. He enjoys having a joke with his friend, but he is not shallow. When he’s with his friends, he is the one who leads them because he is very thoughtful and sometimes charismatic.
