Clara revealed why she was promoting with the name Clara rather than her real name Lee Sung Min on the September 12 installment of JTBC's 'Entertainment Exclusive.'  

She was asked, "What does Lee Sung Min mean to Clara?"  She replied, "I think this is the first time I received this question.  I think Lee Sung Min to Clara is yet another Clara that created Clara."

She revealed that for nine years, she promoted as Lee Sung Min, but received little recognition from the public.

Clara added, "If the actress Lee Sung Min was a repressed and daunted Lee Sung Min, the Clara right now is carefree.  From my early debut, I wanted to be active as Clara.  If you look at the interpretation of the English name, Clara means 'bright.'  I really liked that name because I felt like it matched my personality well."
