Describe the most typical Villainess reincarnation manwha

I have nothing against these types of stories, I just like making fun of stuff. I’ll start.
Mc; reincarnated into the smoking hot bod of some villainess in a sad reverse harem story. Said villainess is always the daughter of a duke, engaged to the crown prince, and dies by execution. Says she isn’t gonna get involved with the MLS and Fl. Tries to achieve this by giving up immediately, avoiding the main characters like the plague, and being a generous person. Everyone becomes obsessed with her after a while (sometimes even the FL) and basically gets a reverse harem of her own, however is too block headed to realize she has changed the plot.

ML; Nines times outta 10 is gonna be a black haired, blue eyed edgy prince with a horrible family. His dad, the King, is always gonna be an ass and his mom has a 50/50 chance of being either deceased but an amazing kind woman in life, or a straight up dumb bitch. Usually if she’s a bitch she’s gonna have another son who’s an ass like her. He probably caused the MC’s death in the original book or otome game, and openly shuns her in the manwha. The only time he starts paying attention to her when she actively avoids him. Bonus points if he’s an amazing swordsman and is planning to kill his mom.
