Angnyeo Karunaga Jagajyeosseoyo

After ten years of pretending to be the count’s hated daughter, Karuna is ready to escape. However, her plan goes sideways when she gets attacked. In order to save herself, she takes a potion that promises to turn back time. Instead, it transforms Karuna into a child. Things get even weirder when she witnesses a giant wolf transform into Duke Vykeld, and now she must hide out in his isolated manor. After terrorizing nobles for ten years, can Karuna handle being a child again?
