Return the Bride. A Trap for the Isekai Girl

He is the heir of a ruling magical bloodline. One of the strongest sorcerers. Dragonborn. By tradition, only the woman whose gift equals his may become his wife. So when the heir’s fiancée lost her spark, the engagement was immediately broken off. I ended up in this world by accident—in the body of his former chosen one—and I’m forced to live someone else’s life. There isn’t a single drop of magic in me—at least that’s what everyone around me believes. So why does he keep following me? Why does he stand in the way, again and again, messing up everyone’s plans? After all, he himself rejected the fiancée. Has he realized that I’m not who I claim to be? Or is it something else entirely?
