She serves as an ash maid and suffers nonstop harassment from a jealous rival. The girl unlocks her rare thread magic gift and gains renown. Once she bears the heir’s child, cruel schemes are set against her. The heir stands up for her openly, reveals she was the one who saved him three years prior, punishes all wrongdoers, and asks her to be his wife in an official engagement.
