The Novelist is the Villainess

Marceline is a pantser who writes dark fantasy stories, but when she hit a writer's block, she couldn't sleep for days and died of a stroke, regretting that she had not lived to see the conclusion of her book. With a twist of fate, this dying wish served as the key for her to traverse worlds, finding herself reincarnated as her book's villainess. As an author, this unexpected turn of events felt like a surreal dream come true - the chance to live her life through the eyes of one of her characters. However, a foreboding truth still remains: in most tales, villainesses meet their tragic end. Will Marceline be able to rewrite her story's destiny or she'll succumb to the narrative of villainy itself?
