Echo in Fog Alley

In a fire, Lin Shen lost everything, leaving only an old diary filled with "Xiao Wan". He became a restorer of old objects and spent his days guarding memories in deep alleys. One rainy night, an anonymous package delivered half a diary and old photos. The figure he had been searching for for ten years finally had traces. At the same time, on the city's late-night radio station, anchor Su Wan uses her voice to heal loneliness, but no one knows that she is also looking for the lost past. Separated by an alley and a frequency away, they are so close, but they don't know that each other is the answer that the other has been waiting for ten years. Old things hide secrets and echoes convey feelings. After ten years, they will finally meet each other again deep in the fog alley.
