Paris needs saving, but when you have two heroes who don't get along, the city might need more help than it thought. Bitter rivals with or without the mask, Adrien and Marinette want absolutely nothing to do with each other. But it won't stay this way for long because, as the saying goes, there's a fine line between love and hate… ― LadyNoir/Adrinette/MariChat/Ladrien, rival!au.
