If i remember correctly it's a reincarnation manga where fl reincarnates as a princess in a world where boyxboy couples are really common. The one who is most likely to be the male lead was her knight (black haired). I also remember fl and her brother not getting along because of misunderstandings, because he thinks she hates his lover (a commoner),not quite sure about this last part
Lend me your wisdom pls
