When A Snail Falls in Love

When the razor blade incidents begin to plague Lin City, the local Criminal Police Force is thrown into a state of heightened alert.

Amidst the tension of the investigation, she must navigate the complexities of human nature and her own developing connection with her partner, Ji Bai, as they race to stop a predator hiding in plain sight.
