The Heir's Flash Marriage Pact

Nina Ainsley, abandoned by her family, marries Zane Luther in place of her half-sister. Onlookers see this as a union with a mentally impaired young master. Nina's exceptional medical skills recuperate Zane's health. Zane, appearing disabled, is actually sharp, disguises his identity. They form an alliance, handle family disputes, fight back against Nina's birth family, and reclaim what belongs to them.
