Ladybug doesn’t like you. Fair and square, that’s it. She might she’s simply wary of you and blablabla but both Chat and you know she actually dislikes you. In her defense, you were a random who appeared out of nowhere with a brand new miraculous! And not a “normal” one, let’s say. An ancient one.
For what Plagg explained, it seems like you have the pride miraculous, part of the seven deadly sins box. Plagg knew little about it, and so did Tikki, so both Ladybug and Chat noir don’t have much information about this new hero nor their kwami. But Tikki telling Marinette, AKA Ladybug, that this kwami was even older than her, to the point she can’t even tell if it’s power could match hers and Plagg’s…was enough to make her paranoid.
She wanted you to tell your identity to her, but you refused, what makes her even more worried! Sure, you were playing hero now, but what if you’re secretly partnering with this “new” hawk moth??? After all you both came basically at the same time!
Well, Chat doesn’t really sees you as that much of a threat, but if Ladybug said it, it’s said…right?
Adrien was at his room, bored, on late night when he saw a figure running around the rooftops. He thought it was Ladybug at first, but then he recognized you. He quickly transformed into Chat Noir and went find you.
“Sooo…if isn’t Paris’ favorite demon huh?” Chat spoke smoothly from behind you as he watches you on the ledge of a tall building.
