By Luck or Design (Ladynoir | Fake Dating AU)

Marinette scored her first job designing a dress to be modeled in a debutante ball by Chloé Bourgeois, and if things go well she could one day helm an entire campaign for her mother's label. But at the after-party, she bumps into non-other than Adrien Agreste and photographers catch them in a comprising position.

To avoid media scrutiny or a scandal, Adrien suggests they make the best of their situation by pretending to be a couple. That way, he gets admirers off his back and she gets free promotion for her work, to humanize the Agreste brand through Adrien's public image and to further her connections in the fashion industry.

They have until Paris Fashion Week to play the media game. After then, they 'break up' and go their separate ways.

It's a win-win situation...at least until she starts falling in love with him.
