In relation to her using her stage name even while doing activities as an actress, IU said, "I feel more of a responsibility while using my stage name.  Also, I like that I can think of my personal, private life separately from my work life."

She mentioned the difference between the two selves: "IU thinks more and is becoming smarter bit by bit, whereas Lee Ji Eun thinks less and is becoming dumber.  However, I like that.  When I am Lee Ji Eun, I express my feelings simply and become a bit more honest in relation to other people."

Her drama will be out on November 20 so check it out to see her not as IU or Lee Ji Eun but as her character Kim Bo Tong!
