As a reader, the last thing Su Su wants is to see a story end badly.
But after an accident, she transmigrates into a book, landing in a series of novels where the plots and characters have all gone off the rails, ending in a rushed finale.
The heroines are all beautiful, powerful, and tragic. After being framed, they set out on paths of revenge and go too far, straying further and further toward the brink of corruption until the protagonists become villains and the whole story ends badly.
Her job is to use love and warmth to change the heroines, keep them from turning evil, and salvage the endings.
System: Ding! Congratulations, Host, you've acquired the "expendable character" role. Save the story and prevent a bad ending!
Su Su: ...You said I'm an expendable character. How am I supposed to save anything?!
