Marinette's class has graduated from high school. All of them will go to different schools, that are in completely different parts of France. Her best friends, Alya and Nino, are going to go to the same school, but far away from Paris. Marinette, on the other hand, is going to go to the same school as none other than Adrien Agreste, who, through the years, finally accepted that he has a crush on her and admited it to Plagg. What they don't know, beside their identities, is the fact that they will be roommates in collage.
