Please Don't Believe Her 2004

On the surface, Young Joo (Kim Ha Neul) ) is just an ordinary girl with a cute appearance and cheerful personality that everyone loves. However, the real Yingzhu is a slippery female liar who tells lies constantly. One day, she took her beloved wood sculpture to Busan to attend her sister's wedding. On the way, Young-joo met a man named Hee-cheol (played by Kang Dong-won). Hee-cheol's innocence and simplicity attracted Young-joo's attention, so when the heirloom ring he planned to give to his girlfriend was stolen, Young-joo was determined to help. However, fate is not as good as fate. Not only did Yingzhu suffer heavy losses, she was mistaken for Hee-cheol's girlfriend by accident. She moved into Hee-cheol's house and quickly became involved with Hee-cheol's family. As time goes by, Yingzhu, who is under the cover of a false identity, actually falls in love with Hee-cheol. How should she deal with her feelings?
