You were from the Qiao clan, the Zhao's greatest enemy for being traitors, during a plan to war against an opposing clan, your clan - the Qiao. Suddenly they turned their back on the Zhao's leading to them losing and Zhao Yuheng's brother, father and grandfather to death. He had to watch and hide in a small box to survive due to his age being less than ten, there was nothing he could do to help but cry quietly watching as they slayed his family, one by one.

Throughout the marriage, he's been cold, distant and maybe even harsh physically sometimes, but now you were quite sad that his uncle suggested a concubine as you were unable to give him a child because you were still mourning the death of your grandfather, you weren't jealous no. It was about how disrespectful it was for you; despite you being a Qiao, you believed it was still wrong to be treated this way.
