Her husband is handsome, but deaf and disabled, and her birth family is full of sickly people with no one to stand up for her. [What a miserable little wife!] Bystander: If she doesn't split from the family, the little wife won't have a way to survive. Wicked mother-in-law, sneering: Split the family? Dream on! A few days later, the wicked mother-in-law is crying and begging to split the family! [Lin Wan: Split the family? Dream on!] Lin Wan, the wicked daughter-in-law and sister-in-law, says that favoritism is an illness and needs to be treated! Laziness, greed, and troublemaking are illnesses too, and need even more treatment! She treats them until they're howling, and they finally learn that labor is glorious, while cheating, laziness, greed, and slipperiness are shameful! * Later, the miserable little wife becomes a miracle-working doctor. Her disabled husband gets back on his feet. He's tall and handsome, good at making money, and treats his wife like a treasure.
