Shanghai outside the window is lit with thousands of lights, and there is a life under each light.
And in this house, there are two patients.
They are abnormal, unhealthy, and do not fit any textbook love template.
But they are together.
And——
They will always be together.
Because in this world, there are some locks that can only be opened by specific keys.
Shen Yanqing's key was born to open Jiang Yuan's lock.
The shape is weird, the teeth are messy, and it jams, rubs, and makes harsh sounds when inserted.
But it can turn.
That's enough.
