Seven Days Until the Condemnation Ball – intro video

You wake up as the villainous noblewoman of a novel. The book says that at the ball seven days from now, your fiancé will read out your crimes in front of everyone, you'll be exiled, and you'll die on the road. But now the one man who should hate you most is standing beside your bed: “At the ball seven days from now, stay at my side. Don't leave it for even a moment.”
