Having an intensely competitive streak, she will be bothered all day if she feels that someone got an advantage at her expense. She has big ambitions and desires.
But behind her tough demeanor, there is one thing about her family that she wants to hide from everyone. It’s the fact that she lives with her stepbrother and stepsister when her dad remarried 10 years ago.
As her wedding with Kang-pil, the son of Chairman Han, approaches, she is not happy that Min-jung recently returned from America to live with them.
