The City of Fog and Proof

Now in his thirties, Wu Hongyu is no longer the spirited young man he once was. The fire in his eyes has dimmed, leaving them dark and deep.

Then one day, he took on a murder case. A mysterious woman appeared, and the truth about the past slowly came to light as the investigation unfolded.
