So at this point I just have to assume that every interaction Marinette and Adrien have is Adrien thinking that Marinette is a god of weird, surreal humor.
Why did Marinette give me a pottery wheel and then immediately throw it in the garbage? Because she's hilarious. Marinette's turning my car down because she's taking coleslaw? lol bon appetit. Marinette calls me hot fifty times in weird stuttering sentences before ultimately answering my question with something normal like "yeah dogs are great"? She's so funny. These are the greatest jokes. I never have any idea where these conversations are going and I love it.
I honestly can't even blame him. I'm taking back his oblivious card. It's so much better in my head that he just thinks she's the funniest girl in school.
