Why do I keep finding these stories?

So many of these stories I find are so much like ones I've written. This one is similar to one I wrote where the girl in the story ends up in a book where the villain was actually innocent but in the book she was written like she was the villain and the true villain was the heroin. Everything that was happening to both girls was blamed on the "villain" and only her. So she was executed. The other half I wrote that the girl is reborn as the "villain". She altered the story from the early years. Her parents were shit before but with the changes they were worse. She leaves with a ton of money and makes life better for the Kingdom across the boarder and ends up with the that Prince and the true villain is at last outed.
