Taekyung’s life has been in a downward spiral for a long time. Shouldered with the responsibility of paying the bills and the hospital fees of her only sister, she is barely surviving paycheck to paycheck. It’s hardly surprising that she resorted to borrowing from a loan shark. The true surprise, however, is when she discovers that the loan shark she owes money to is the father of her old high school classmate, Haejoo. Delighted with their reunion, Haejoo makes an irresistible offer: she’ll clear Taekyung’s debt and take care of all her financial needs… in exchange for Taekyung herself.
