What if Ladybug and Cat Noir found out about their secret identities? To beat a villain, Ladybug calls on nine superheroes, when all she needed was Cat Noir and his cataclysm. But she couldn't call the latter, as she still doesn't know his secret identity. The Celestial Guardian of the Miraculous finds that this situation cannot go on. It is too dangerous to leave Cat Noir's Miraculous in the wild with a stranger. If Ladybug is to remain Guardian, she must find a way to tell Su-Han who Cat Noir really is. Someone has to know, and have some level of control. Faced with this ultimatum, what will Ladybug do?
