Rate-8/10 This drama is good. It's kind of cliche with the rich guy poor woman thing but the story line is good. I remember I have a huge crush on Baek Seung Jo xD Although I sometimes find Oh Ha Ni is annoying since she always try hard to get Seung Jo's attention, the plot is still amazing. Soon after, you will definitely fall for her character
