Then he could try to use Adrien's identity as Chat Noir to further his own business or social standing in some way, creating a lot of internal conflict for Adrien.
He could also start acting out of character. Maybe he becomes more competitive towards Luka. If they are both in a band or something, Adrien might push himself harder to be better than Luka just to get Marinette's attention. He could also be more snappy or short - tempered with Luka, even if he doesn't mean to be.
