Looking for a bl

Im looking for a bl thats completed, if i remember it correctly its abt a cop (bottom) who encounters a criminal who goes to jail in the first ch and falls in love w the cop at first sight. And their parents r also together.
A scene i remember is when the criminal catfishes him to see how he acts to other men.

Sorry if this isnt enough info but its all i remember.. （/TДT)/
