Chatnette for five headcanons, too! Gooo!
Marinette always sort of knew that if it wasn’t for Adrien, she would have a crush on Chat Noir. He almost dies laughing when she mentions that after learning his secret identity.
It doesn’t take long at all for Marinette to learn to keep some extra pastries stashed in her room because Chat eats like a sumo wrestler. He claims the scent of the bakery downstairs makes him hungry.
Marinette is the WORST backseat gamer Chat knows, and he makes a point of teasing her with it. She claims she totally isn’t, but they both know better.
The first time Chat claims to play the piano, she doesn’t believe him at all. When he takes her to a completely silent music store and shows her, she’s floored, but the way he looks playing it is something she’ll always remember.
Marinette knows Chat regularly cuddles up to her when she goes to bed, holding her and stroking her hair, leaving when she falls asleep. She doesn’t know that he kisses her before he leaves, murmuring, Please don’t ever leave me. You’re the best thing that’s ever happened to me. His parents’ relationship doesn’t inspire much confidence in him in that aspect, after all.
