Otomege Sekai wa Mob ni Kibishii Sekai desu

After dying, Leon is reborn in the world of an otome game, where women hold power over men. Most men are treated as stepping stones for women, with the notable exceptions of the handsome romantic leads, a group headed by the crown prince. Leon wants only to live quietly in the countryside, but he has an advantage: knowledge of the game from his previous life, when his adventurous sister forced him to complete it. Using what he remembers, he sets out to rebel against the women and the attractive men who dominate this strange world.
