A more mature(perhaps nearly a year older?) Harry managed to catch Pettigrew in 1993 and free Sirius, who is cleared of all charges, and promptly takes Harry to live with him, however, he doesn't want to live in Grimmauld Place so he goes to his family's summer house in France, one Chateau Noir, that's down the road from another manor, where one of Sirius's acquaintances lives.
Trying to find a way to not leave Harry alone while he treats himself, Sirius hires their eldest daughter to tutor Harry, enter Fleur DeLacour, who is surprised the young man is immune or very resistant to her allure, she helps him learn French(by sometimes taking field trips) and they end up connecting over social troubles, a similar taste in music and Harry's cooking. He ends up connecting with her whole family(Gabby adopting him as the older brother who spoils her) and Fleur ends up helping Harry carry himself better and focus in his studies, while Harry helps Fleur have fun and teaches her how to cast a corporeal Patronus, as the weeks pass, they become interested in each other, and eventually fall in love. As Fourth Year commences at Hogwarts, Harry and Fleur are happy they are going to be together during the year. How will the School Year and the Tri-Wizard Tournament be different with Harry and Fleur dating?
