Kris thought he's got everything a person would want in their life. 

Money, good looks, friends, and of course a loving family. He lived in his own Neverland until it all came crashing down in a blink of an eye when her beloved mother took her own life becuase of his father's past mistakes. The once warm and friendly boy became the cold and stern man who built a protective wall around him higher and stronger than the Great Wall of China. He thought his father could not get any more of a than he already is but he thought wrong because he decided to let the "past mistake" aka Krystal Jung live with them.
