Marinette: *smiles*
Adrien:

“tis a visitor,” i muttered, “dummy thicc, and nothing more”
I haven’t seen anyone talking about it but an official Pokemon twitter ran a poll on ‘who would you like to receive Valentines chocolate from?’ and the winners were N and Elesa!
If the gum incident had never happened, I want to believe this is how Mari would have reacted when meeting Adrien for the first time. Both feeling comfortable enough and just fooling around each other.
