Where Did This Unlucky Supporting Female Character Come From?

"No one can step into the same river twice," but you can slip on a banana peel and fall twice! The second time, I transmigrated outright! Transmigration would have been bad enough, but I transmigrated for such an embarrassing reason. That would have been bad enough, but I transmigrated into the villainess. That would have been bad enough, except the body's original owner is still here! Heavens! Do you really have to torment me like this?! In this vast martial world, humans and ghosts mingle. Who are the righteous ones? Who are the villains? What is good, and what is evil? I want nothing more than to escape my fate as the villainess. Will I get my wish? A wicked, devilish fiend, peerless martial arts that shake the jianghu. What? There's another fiend? I'm out of here! The more I try to escape, the deeper I get. I struggle, struggle, struggle, and can't struggle anymore. I'm not asking for much. I just want to live in peace... Enough, enough. I'm tired. A transmigration story set in a fictional martial-arts world. Newton's coffin lid can't stay shut! It's a humorous story, but the plot isn't one-note. I hope you enjoy it! Theme: Enjoy life while you can, and let go when it's time.
