When a cold restorer of ancient books meets a hot-blooded criminal investigation police officer,
An old case is involved,
He clings to old things and is trapped in the past;
He chases the truth and carries the guilt.
In exploring the truth, there is healing and redemption for each other.
The green alley hides the warmth, looking for light and meeting a close friend,
All I want in this life is to be by your side, the fog will clear and the clouds will clear, and you will live in peace year after year.
