HP Rozier Who Doesn't Want to Ride a Broom

Ps.: Two male protagonists, no CP, everyone has a single male protagonist, all CPs are removed. Slytherin's favorite heartthrob. Even though they know that the male protagonist has a very bad character, some people already like him wholeheartedly. Gabrielle Rozier is the only heir to the French Rozier family and the most beautiful rose in the Rozier family. But something unexpected happened in his life and he was sent to Hogwarts. The longer he stayed at Hogwarts, he found that things were getting more and more complicated. The greatest white wizard seemed to treat him differently, and the one who was imprisoned in Nurmengard always looked at him with special meaning. Not only that, he was also surrounded by many strange people, making his life full of troubles. But none of this matters, because he is the most gifted genius in the history of the Rozier family. He will understand them, become them, and control them, all for the glory of pure blood.
