After Transmigrating into a Novel, I Blew It Up

Transmigrating into TV Shows or Books

I want stories where the protagonist transmigrates into a good TV show or movie. They shouldn't villainize the original heroine, and ideally shouldn't break up the original couples. If the original story has regrets, those should be made up for as much as possible. The protagonist shouldn't be a dumb, naive sweetheart, but should be lively and cute rather than overly serious. Mainly, I feel like it's been so hard to find anything good lately.
