Real Family Found Me, Now Enemies Fall

Isadora, adopted by the Sollow family, is falsely accused of poisoning her adoptive brother and driven out. She actually is the lost heir of the Silverwood family and the legendary healer X. After leaving, she saves Sebastian from a soul-tearing curse, then her three brothers see her silver-leaf pendant and bring her home. Her adoptive sister Ophelia plagiarizes her potion recipes and allies with Isadora's cousin Celestia to hire assassins. With Sebastian and her brothers protecting her, Isadora survives every attack, and reclaims her place. At the return ceremony, her family exposes Celestia, cuts ties with Sollows. And Sebastian proposes, she says yes. Finally home, finally loved.
