Abandoning "love at first sight", the male and female protagonists intersect due to an "ancient book theft case". The initial stage is full of wariness and temptation, and the emotional development gradually heats up with the detection of the case, incorporating the depth of "trauma resonance" and "mutual redemption".
The case design combines "antique culture" and "modern crime", such as discovering family secrets from hundreds of years ago by restoring ancient books, or using auction house transaction chains to track transnational crimes, avoiding the traditional suspenseful single case solving model.
