Marrying the Sickly Young Master in a Period Novel

One-line summary: A sickly young master gets stronger thanks to his wife's lustful inner thoughts. Ji Yunshu transmigrates into a book set in the 1960s, where her whole family is awful: An alcoholic, abusive father, a mother who favors sons, a sister-in-law who exploits her, a freeloading older brother, and a love-struck version of herself! There's no way she's going to be a love-struck fool. Adults don't change, they just filter people out, and she can do without these terrible relatives! Ji Yunshu beats up her drunk father, chews out her clueless mother, spends her brother's secret stash, ruins her sister-in-law's good job, kicks her scumbag boyfriend to the curb, and marries a sickly young master with whom she was betrothed as a child, taking a huge bride price with her. A sickly husband is great. A sickly young master is even better. He's rich and won't live long. After he dies, she'll inherit his estate. Wouldn't that make her a rich young widow? Ji Yunshu laughs like a pig in her dreams as she waits for her sickly husband to kick the bucket... Si Jinnian comes from a distinguished family and wants for nothing. Unfortunately, he was premature and born with a congenital weakness. His family feared he wouldn't survive, so they consulted a fortune-teller about his birth chart and arranged a childhood betrothal for him. They were told the girl would bring him good fortune, and that marrying her as an adult would bring him health. When it comes time to marry, Si Jinnian is deeply reluctant, but he can't bear to upset his family, so he agrees. To his surprise, starting on their wedding night, he keeps hearing his bride's inner thoughts... Look at that pale skin and slender frame. A sickly beauty really is the best thing in the world. I want to kiss him! Whoa, broad shoulders, narrow waist, long legs. Looks slim in clothes, but there's muscle underneath. Amazing. I want to touch him! That full chest, those toned abs, that sexy dip in his lower back. So hot. I want him! Whenever Si Jinnian hears Ji Yunshu's lustful thoughts, his heart races and his ears burn. How can a girl be so shameless? But she loves me so much! I'll forgive her. The Si family notices that ever since Si Jinnian got married, he's become a different person. He isn't picky about food or bothered by bitter medicine. He follows the doctor's advice and works out, and his health improves day by day. His wife really does bring him good fortune, and the Si family pampers Ji Yunshu to no end. Until one day, Ji Yunshu complains in her heart: All looks and no substance. Why hasn't he kicked the bucket yet? I want to be a young widow. I want to find a handsome man to worship! Si Jinnian's eyes go red. He corners Ji Yunshu against the wall, grips her chin, and grits his teeth. "You want to be a young widow? You want to find another man to worship? Forget it! I'm telling you, I won't die. And I'm not all looks and no substance. I'm very capable. Feel for yourself..." He grabs Yunshu's hand and pulls it down... Theme: Stay away from toxic people, cherish life, and love living.
