Snow in a Cage

Shen Zhaoxue saved Yu Zhao, giving her medicine, an identity, and a way to survive, but also leaving countless invisible chains around her.

Yu Zhao hates being controlled, yet gradually realizes that every time she resists, Shen Zhaoxue only closes her hand more gently, and more dangerously.

They are not simply saving each other. They are taming each other.

Shen Zhaoxue thinks she is raising a future enemy, only to discover in the end that what she has raised is no blade, but a fire capable of consuming all her reason.
