Magic-setting Stories

In every novel, there is the villain and protagonist, and in each story where the protagonist reincarntes, "most likely as a villain", she will definetely avoid any death flags...blah, blah, blah. In the end, she either becomes friend with the heroine or the heroine is a two-faced scammer. But what if the so-called villainess and heroine are people who are trying to act out their roles....just without a script.
