Marinette, exhausted with her work as Ladybug, class president, sewing projects, working at the bakery, crushing over Adrien, and school; she decides to make herself a hamster hoodie similar to the show Himouto! Umaru-chan to help her relax. Not only is it relaxing, it turns her into a lazy loli who is content on binge snacking and playing video games. The only one aware of this double life is Chat Noir, who can't believe Marinette could be lazier than his kwami.
Everyone plays themselves.
