The Duke's Forgotten Wife

DramaBox synopsis

Amber Roe, a tavern maid, saves a dying knight named Kyle—awakening the dormant witch power in her blood. He heals, but after they part, he cannot remember her face or name. Five years later, she opens an apothecary in the capital with his daughter, and enters a contract marriage with Kyle, a duke hiding his identity. She doesn't know the man before her is the one she's waited five years for—and the woman Kyle has been searching for, whose face he can't recall, is her.
