Adrien isn't the literal ball of sunshine and obliviousness he projects to be. He knows all too well about the importance of masks and the way people understand and categorize him in the 'dumb pretty blonde' category. This is especially helpful when he can pretend obliviousness when he doesn't know how to let down Marinette, well he didn't know how to let her down before, but now he doesn't know if he wants to let her down or not. Yet, his heart still belonged to Ladybug didn't it? What happens when one day checking up on his princess as Chat, he discovers his lady and princess are one and the same? And that his stupid advice of taking the high road is what is causing her so much distress? It's a good thing Felix is coming to visit, after all his cousin was the best at masks and manipulation.
