The female protagonist Lin Wan is a psychological counselor who appears to be gentle and healing, but in fact she suffers from severe post-traumatic stress disorder (being abandoned in childhood); the male protagonist Shen Du is a former criminal policeman who was disabled in the line of duty. He lost his left leg in the line of duty and has since closed himself off and refused all help. The two met in each other's darkest moments, saved each other, and became each other's light.
Not bad, hope to update soon
