"They used blood to build a cage for her, and she used the cage to lock everyone in."
Ten years ago, the Shen family was destroyed overnight. The eldest daughter, Shen Wan, was adopted by Chen's father as his "adopted daughter" and became the nominal sister of the Chen brothers, but was actually a forbidden concubine. Ten years later, she returned with debts and hatred. She used her bones as blades and kisses as contracts to turn the former prison into a Shura field where the three of them fell together.
