Isekai : top book in the genre

My cheating husband pushed me out of a window to take my apartment. The end? Not quite. I woke up inside a novel I had been reading the night before… As the villainess—destined to lose everything in the end. Now I’m the daughter of a fox-shifter clan. The fiancée of a dragon prince… who is fated to abandon me for the “white swan”—the story’s perfect heroine. And according to the plot, I’m supposed to be disgraced, married off to a pathetic noble from a fallen house, and left to rot in the provinces. Sounds easy enough: just don’t be evil, right? Except the real snake here turns out to be the heroine herself… and for some reason, she’s determined to destroy me. A villainess, you say? Fine. But this villainess is done playing by someone else’s rules.

Opening your eyes in the body of a baby, growing up in the Beast's castle, constantly listening to all sorts of whispers? Well, it happens, but the appearance of a male fairy (what is the correct name for them?) is too much. He also constantly follows me, clings to me and tries to kidnap me! And how many times have I told him: "You made a mistake with the beauty, Mr. Fairy!", but this only encouraged him... Now I will have to learn many secrets of the past related to my parents.

I was born the only heir to a family of heroes, so my purpose is to save the world. My marriage was to help achieve this noble goal. I have no romantic intentions, but something seems to be drawing me to this man! He is a villain, it is in his blood, but why does he look so much like someone I do not want to meet in this life? I will live this life only the way I want, and I am not going to make the mistakes of the deceased Ariadne! I am not her. Or is it...?
