Marinette works for the FBI and is trying to get information on an organization participating in illegal overseas affairs. She is assigned to work for a major fashion company who’s CEO is suspected to be part of the illegal activity.
It’s her job to try and get some information from her boss and possibly get into the organization. Adrien is visiting town and becomes a hindrance (or an asset??) to Marinette’s mission. He falls in love with Marinette and it becomes messier than her field of work.
Theres actually two more pages to this but I’m too lazy
