The Blind, Crippled Prince Consort Is Cured by a Cannon Fodder Daughter

(Both are each other's only one) Su Wan Ning wakes up after a car accident in a novel about a pampered heroine, reborn as the legitimate eldest sister, a disposable side character. When her willful younger sister trespasses into a military camp, the elder sister cuts her hair in her place and takes her punishment. The family gives up their hard-won merits to ask the emperor to arrange her marriage to the cold-blooded God of War, the youngest prince and the kingdom's most formidable general. But when the wedding sedan arrives, the God of War has become a crippled prince. Her younger sister refuses to marry him and even demands that Su Wan Ning take her place. Su Wan Ning is at her breaking point. She puts on her wedding dress and leaves the Duke of Zhen Guo's residence at once. She won't be anyone's disposable side character anymore. Whoever wants the role can have it... //// Everything is going well since she married into the imperial family, but Su Wan Ning knows from the novel that every prince in the royal family is a devoted, long-suffering spare for the heroine. The benevolent crown prince is a lovesick fool who gives selflessly for a woman who will never love him back, and eventually dies saving her. Ever since Su Wan Ning married into the royal family, he's been too busy to do that. Instead, he follows her around all day. “Just try coming to my residence again!” The second prince is the warmhearted male supporting character, running from one end of the land to the other at the heroine's every request. Su Wan Ning cautiously asks, “Want to help me clean out the crown prince's residence?” The second prince: “...I don't see why not.” Since Su Wan Ning married into the royal family, the fourth prince has been thinking of nothing but finding delicacies from all over the land to feed his third sister-in-law. The fifth prince is determined to claim the throne and marry the heroine, but in the end he's stripped of his title and reduced to a commoner. Su Wan Ning pulls out a stack of banknotes. “Money makes the world go round. Women only slow down my money-making.” The fifth prince: “?” Why is my third sister-in-law talking nonsense? Ever since she married into the royal family, they stopped circling around the heroine. The heroine: “?” Where did all my suitors go? Why are they all surrounding that woman who's inferior to me in every way?
