I was reborn as a villainous young lady, but since I don't have knowledge cheats or can think of any ways to avoid my fate, I decided to give up on everything and just dote on my younger brother instead... and somehow ended up acquiring refined manners. By the way, the reason is that the villainous young lady's "brain" and "body" specs are incredibly higher than in my previous life. An extremely convenient and happy ending. A grand finale where no one becomes unhappy. I'm also posting this on Alphapolis.
