Ivy surrounds the wall, and sharp knives depend on each other.
Xie Yu and Bai Xiang are two symbiotic pawns in the PCA killer organization.
Use the tip of the knife as our daily routine, use silence as our confession, and support each other in the boundless darkness.
The vines are fetters and shackles; staying together is salvation and a cage.
They share secrets and scars, share light and the rest of their lives.
The cold forensic doctor attacks the indifferent executioner in the dark.
Bai Xiang
Intention: Two-way redemption
