Trap of Love

The lead heroine forges FBI Agent credentials and arrives at the crime scene to retrieve the victim's phone, which contains messages about providing illegal documents for the victim. She does this because she doesn't want to be linked to the murder. Due to the forged documents, she is mistaken for a real Agent and is pulled into the investigation. At the crime scene, she sees the man—a detective - with whom she met at a bar a few days earlier and had a One-Night Stand (ONS). Now they have to work together on the case, and she has to ensure she doesn't reveal that she is not a real Agent.
