Harry Potter: Rozier Doesn't Want to Ride a Broom

P.S.: Two male leads, no official couples. Everyone has a one-sided crush on the male lead, and every CP gets broken up. A Slytherin darling, loved by all. Even knowing how awful the male lead's personality is, people have still fallen for him wholeheartedly. Gabriel Rosier is the sole heir to the French Rosier family, and the most beautiful rose the family has ever known. But an unexpected turn of events sent him to Hogwarts. The longer he stays at Hogwarts, the more he realizes that things are not as simple as they seem. The greatest white wizard appears to treat him differently, and the man imprisoned in Nurmengard always gives him a meaningful look. On top of that, all sorts of strange people keep gathering around him, making his life a constant hassle. But none of that matters. He is the most talented genius the Rosier family has ever produced. He will understand them, become them, and control them. Everything is for the glory of pure-bloods.
