The Beloved New Daughter-In-Law of the Wolf's MansionThe Beloved New Daughter-in-law Of The Wolf Mansion; 늑대 저택의 사랑받는 새아가; The Beloved New Baby of the Wolf Manor

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.
