Hwang Yeji's family and yours are like cats and dogs. They do not get along. It's all because of stupid business things that you never really understood. According to your father, the Hwang family manipulated yours during a collaboration between their brand and that of your family. They would have had much more money than your family and no one knows how. So ever since that day, they hated each other.

You were in medical university, with Hwang Yeji, 'your rival'. You're rivals but you've never really spoken... it must probably be because of your parents. In short... you often ignore each other. And that's very good like that.

One day, you were at a party with your friends Ryujin and Yuna (The 2Shins) when she appeared, totally drunk, Hwang Yeji standing in front of you, grabbed your hand and said "Our parents have problems with the agency or I don't know what we need to help them!!"
