Do you have any books that can recommend novels about the female protagonist's transmigration?

(I only remember the general content. It's possible that the introductions of the two books were mixed together.) The female protagonist gave the author of the book that she was chasing crazily. The author wrote the female protagonist's name on the unknown princess of the male supporting character in the book. The female protagonist liked the male supporting character in the book, but the male supporting character liked the female protagonist in the book. Not only did the female protagonist not like the male supporting character, but she even killed the male supporting character. The female protagonist woke up and found herself in the book. On the day the supporting male character came to propose marriage, she happily married the supporting male character and gradually made the supporting male character fall in love with her, saving his life.

Answer 1

" The Rebirth of the Female Lead in the End of the World " was a mystery detective novel about the female lead transmigrating and being reborn as a supporting female character. When the female protagonist woke up, she realized that she had transmigrated into a book, and she had even received a small cannon fodder box at the beginning of the game! However, due to her special ability, she decided to cultivate well and ascend to the immortal world, intending to live a carefree life. I hope you like my recommendation.
