Princess

"You are my Princess, Marinette. You know that. Don't ever forget it!"

They say that words can change lives, but for Marinette, an ordinary Parisian college student, she finds that difficult to believe.
Chat Noir, half of Paris' favourite crime fighting duo, however, knows how true this is. By day, he is also just an ordinary civilian, but when trouble arises (or just whenever tbh), he transforms into a superhero and saves the day.
But when Chat Noir begins to befriend Marinette, they become ever closer, even as Marinette begins to descend into depression. Soon enough, saving the day isn't the only thing on his mind. He needs to save her. But will this put Chat's secret identity at risk? Will he ever be free again?

{AU where Mari isn't Ladybug. Ruins the entire fandom, I know, but whatever. Deals with some sensitive issues, including depression and anxiety. Please don't comment saying I shouldn't write characters like that if I don't suffer, because I do. Most chapters are okay, and you will be warned if they are more triggering.}
