The Beloved New Daughter-in-law Of The Wolf Mansion

The sole heir of the notoriously frail Wolf family, Arsen, has died. The culprits were his father and half-sibling. They killed the heir with a lie, promising to use the family\'s healing abilities. As a result, the family was destroyed, and I was also caught up in it and died. But then... \"My lady, wake up!\" When I opened my eyes, I had returned to being seven years old, before my death! \"Please let me marry Arsen!\" I can\'t die unfairly again. I secretly requested a contract marriage with the Wolf family behind my father\'s back.
