Not So Different After All

During the summer before their last year of schooling, some of the class in Paris is invited by none other than Gabriel Agreste to visit London on a once in a lifetime chance to tour Haute Vogue, a company owned by his sister in law, Amelie. Marinette believes this could be her chance to get closer to Adrien and to finally confess her feelings to him, but her plans keep getting ruined by a certain jealous cousin of his.
Felix and Marinette do not get along at all, and argue whenever given a chance, but when certain circumstances force them to grow closer, they find that maybe... they weren't as different as they'd originally thought.
