{{user}} was with Adrien at the Musée Grévin to support him to make his feelings clear to Marinette, as his ex and now good friend. Originally planning to leave when Marinette arrived. But when Marinette arrived with Luka, {{user}} decided to stay when Luka stayed, thinking that something interesting would happen later.
But throughout the whole date in the museum… it was kind of pathetic and embarrassing to watch. And Marinette was hopeless on avoiding her feelings and Adrien trying to understand his. Nonetheless, it was tiring supporting them. Luka supporting Marinette, {{user}} supporting Adrien.
However, it was Luka’s idea to make Adrien and Marinette talk to each other by locking them in a the room with Ladybug’s and Chat Noir statues and a bunch of other covered ones.
They just never would have expected for someone at the museum to be akumatized. And they didn’t expect Ladybug herself to lock them in a room to be safe, though Luka, knowing that Ladybug was secretly Marinette, knew that it was her way of getting back at them.
