Lie to Me () is a South Korean television series starring Kang Ji-hwan, Yoon Eun-hye, Sung Joon and Jo Yoon-hee.
The series revolves around a civil servant named Gong Ah-jung (played by Yoon) who pretends to be the wife of the wealthy hotel heir, Hyun Ki-joon (played by Kang), to impress her former friend. It is directed by Kim Soo-ryung and Kwon Hyuk-chan, produced by Jo Sung-won and written by Kim Ye-ri.
Gong Ah-jung (Yoon Eun-hye) is a government employee of the Ministry of Culture, Sports and Tourism. At the beginning of the series, Ah-jung lies to an antagonistic friend about being married to not lose face in front of her. The lie quickly snowballs (due to several misunderstandings) until Ah-jung realizes that everyone is gossiping about her supposed, secret marriage to Hyun Ki-joon (Kang Ji-hwan), the wealthy president of World Hotel.
Ki-joon confronts Ah-Jung and asks her to rectify the situation as the rumor has spread to even his friends. Ki-joon and Ah-jung decide to take action to squash the rumors, with Ah-jung agreeing to call her friends together so she can confess her indiscretion. When this doesn't go as planned, Ki-joon decides to take legal action against Ah-jung. However, after a series of events that bond the pair, they agree that pretending to be married for a short while would be mutually beneficial. Ki-joon says that in spite of this, Ah-jung's lie is not forgiven, and he threatens to eventually follow through with his lawsuit.
Things become even more complicated when Ki-joon's ex-fiancée returns from France. As Ki-joon and Ah-jung grow closer and fonder of one another over the duration of their pretend marriage, Ki-joon finds himself questioning his commitment to his former fiancée Yoon-joo.
