When Marinette Dupain-Cheng moves to London to complete her fashion training, she ends up moving in with her best friend Félix-and unfortunately, his older brother Adrien.
Marinette and Adrien immediately decide they can't stand each other. Their shared flat turns into a battlefield of stolen remotes, sabotaged cooking, missing toothpaste, and ongoing Nutella crimes. Adrien's friends think it's hilarious that Marinette is completely immune to his charm and dare him to make her fall for him. Adrien never agrees... but he doesn't say no either.
Then, on the spring equinox, the dreams begin.
In their sleep, Marinette and Adrien are Ladybug and Chat Noir-partners who move through the night like they're meant to be. The dreams start long before either of them is ready to admit the growing tension between them when they're awake.
Between late-night banter, unexpected support, and one reckless "f-it" moment, enemies turn into something more. They start a relationship while Félix is away-and hide it when he comes back.
But when Félix's birthday party reveals both the secret relationship and Adrien's bet with his friends, Marinette is forced to choose between the boy she loves and the best friend she refuses to lose.
