FL and ML are both good actors (especially Wu Jin Yan) and perform their roles excellently.
The basic idea (screenwriter and police) is an interesting setup, but it is the only positive thing in the entire script.

ML's behavior towards FL is totally worthless: bullying, dominating, subjugating and derogatory speech ( C-dramas male archetype )
FL, on the other hand, is the female archetype of C-dramas: stupid, helpless and lovesick.

The age difference between the characters is actually about 20 years, but visually it's about 30, so the so-called "romance" mostly evokes pity for FL.

The writers could finally ditch such silly characters and produce something worth watching. Currently, more than 90% of C-dramas are patriarchal garbage.
