Since popular gagwoman Lee Kuk Ju is able to joke about herself, you might think that she's got thick skin. That doesn't seem to be the case as she revealed on 'I Live Alone' that she's actually on the sensitive side.

Lee Kuk Ju also showed a lot of concern for her younger brother. Her brother told her, "I want to become a celebrity. I want to give it a try." She answered, "I don't mind that you're going to do what you want to do, but I worry that you're going to get hurt."

She added, "Neither you or I are mentally strong. As you know when people say hate comments to me, all of it bothers me and I think about it. That's why it was so hard. I worry that you'll face the same thing." The protective sister also carefully said, "If you're only lightly thinking of becoming a celebrity, I wish you wouldn't try in the first place."
