This drama is one of my favorite Cdramas. 10/10..The chemistry, acting, costumes,story and character development are all simply amazing. The ending is sad, yes, but necessary. No matter how much love they have for each other, you just can't be with someone who killed your family and it's not just a normal royal family; Xiaofeng's family is extremely close. They just cannot be. If only Li Chengyin did not force things and let her go, they could have had a happy life someday even if it's separately but alas, he just couldn't let go. Thus, the tragic ending had to happen.
