In your marichat comics esp the recent sin one.... does Mari know his true identity? I'm imagining Mari and Adrien just .... really chum buddies at school Mari unaware Adrien was the one who went down on her. Or him just secretly checking her out.
Yeah, she knows his true identity here (they both do), I actually added “post reveal” tag uwu”” (X)
But not that your ideas are not good! :3
