Learning to care

Miraculous Ladybug Felix X Marinette and Agreste Twins AU. All told from Felix's POV, even though he watches Marinette fawn over Adrien every day it slowly becomes more annoying when he realizes he's caught feelings for Marinette himself.

Nearly a decade later after living with his aunt Amelie not being able to see her he returns to Paris under his father's company to start his own fashion brand. Two things surprise him 1. Marinette has followed her dream to become a fashion designer yet doesn't want to work for the Agreste's (including himself) 2. His feelings still remain just as strong and the anxiety returns with it.
