Meet Adrien. All he wanted to do was live his life being the most powerful wizard in the kingdom. Except he's cursed and a cat. Meet Marinette. All she wanted was to summon her idol, Adrien Agreste, save him from whatever spell he's surely under, have him fall in love with her, get married and live happily ever after. Instead, she gets a cat.

There's a conspiracy afoot in Alya and Nino's class. Akuma seem to be attracted to them. So far everyone has been possessed. Everyone except Adrien and Marinette, that is. After Alix and Kim start an argument, the class start placing bets on when they will get turned. Alya is not happy about it. She has another theory in mind. And she is going to win that bet, one way or another.
