Heungmangnim, Gyeolhon Ppaego Da Haedeurilgeyo!

A heroine reincarnated into the body of Enrica, a powerless noblewoman, faces certain death at the hands of her archduke husband on their wedding night. A kind and mysterious count named Belbrington offers help, advising her to find another husband and accepting her proposal. Enrica’s new path seems unusually trouble-free—her ambitious father accepts her marriage to a man of lower rank, and the archduke takes no action against her for ending their engagement. Yet, these developments feel suspiciously convenient, hinting at an underlying mystery.
