Lee Hyun's sister and main reason for Hyun's hardwork and dedication.


Hayan has a dedication to exceed that she developed to repay her brother's hard work. She has a deep attachment to her brother and shows jealousy at any woman that tries to approach Hyun. She also has a similar work ethic and will take advantage of everything to obtain money.


After their parent's death, Lee Hayan was to be put up for adoption by their grandmother. Lee Hyun resisted and declared that he would personally take care of his sister from that point on. Time pointed to that his grandmother was right when she prophesized that he would regret that decision, as he actually did when times were especially hard. Currently Hyun is grateful he kept his sister at his side and just hopes for her to find a good husband and be happy.
