A Survival Plan for the Villainess Who Transmigrated into a Book

Looking for Stories Where the Protagonist Is Completely an Extra!!!

The heroine ends up inside a book and lives an ordinary life, keeping her distance from the main characters. No following some villainess plot or getting involved with a yandere or anything like that. I want to see a normal life!!
