Pearl in Red

After being orphaned when they were young, Kim Myeong Hui (Park Jin Hee) vowed to protect her younger twin sister Dan Hui (also played by Park Jin Hee) no matter what. However, after Myeong Hui's attempt to raise money for Dan Hui's surgery goes tragically awry thanks to the wife of the Adele Group conglomerate's chairman, Dan Hui decides to take on her sister's identity and get revenge by taking over the company. At the same time, another woman attempts to infiltrate the Adele Group for revenge: Baek Jin Ju (Nam Sang Ji), who lost her father in a car accident, adopts the name of Chloe Lee as part of her own plot. But when she happens to run into her ex-boyfriend, the successor to Adele Group, she may have to change her plans or risk everything unraveling in front of her.
