Love can't be undercover

Amber wasn't too lean into the idea of the FBI even though she had worked for them a charming 4 years. She wasn't keen on romance either, since her occupation never kept them.

That was until she met Tony while working a case in Chinatown. After having to work undercover as a couple for the operation, she falls too deep into the role, and in love with him.

How does she keep this relationship?
