The Villiainess Is Adored by the Crown Prince of the Neighboring Kingdom
Girl isekais into otome game villainess fiance of prince, but too late in the course of the game to change anything. Thankfully she was never actually a bad person. The OG FL & ML still get together, and she ends up w a prince of a neighbouring country, and becomes friends w the OG FL in a great plot arc. I'm not going to sub to the manga though, because I've heard that the drama beyond chapter 24 is intolerable. Super cute thus far, though - I silently applauded at their wedding (only because it was night time)

Villainess Maker
Girl isekais into villainess of a novel she wrote. The OG villainess dies at the hand of the OG ML for the sake of the OG FL. The MC knows this however, so tries to change her fate, only to find that if she deviates from the role of villainess, the day loops. One other person - a mighty demon king or smth (and OUR ML) finds that he is the only other person who recognises the day looping, and reckons it's the god of the world doing it in someone's favour. He finds that person to be the MC, and discovers soon after that he can't kill her. So they make a pact to "take on" god together, kind of - with him disguised as her butler and tutor.
