The Witch's Sweet Contract

A witch clan maiden, orphaned of her mother, is tortured with poisons by her stepmother and stepsister—becoming toxin-proof, her blood a cure-all. Sold off to a fierce hunter (actually an amnesiac noble heir), they marry first and fall in love later, as he dotes on her endlessly. When his scheming younger brother poisons him, she saves him with her blood. Despite stepsister's meddling and a rival hiding the family heirloom, he retrieves it, brings her home to rule, and they live happily ever after.
