A similar case happened to one of the leads who is an orphan at which the director of the orphanage turned out to be the antagonist.

In Player, the world of solving crimes are between the swindlers and the bad guys whilst in accidental detectives, it's between detectives n bad guys, but the chemistry and comedy in both movie/drama gave me similar vibes.

The feeling!
the relationship between the leads for both dramas is somewhat similar. They got the pride & prejudice kinda relationship, where the girl always skeptical about the boy's dark character and emotions.
