The Cannon-Fodder Sister-in-Law in the 1960S [Book Transmigration]

My other story, The Eighties' Burden: A Transmigrator's Tale [From Ancient Times to the Present], is now underway. Come give it a favorite, lovely readers~ Su Xi transmigrates into a book, becoming the troublemaking "younger sister-in-law" of the villainous big boss in a period novel. The original owner had beauty but no sense, and threw herself wholeheartedly down the road to becoming a cannon-fodder character. She considered humiliating her only older brother the greatest pleasure in life, simply because he was gay. Eventually, her brother could no longer bear the pressure and died by suicide, leaving the original owner to suffer a gruesome death at the hands of her brother-in-law, the villainous big boss, who came to take revenge. The peach blossom spirit Su Xi, now transmigrated into the story, trembles with fear... Warnings: This story is set in a fictional world, a very fictional one. My writing is limited, so don't take it too seriously! The heroine is not all-powerful. This is a fluffy, brainless wish-fulfillment story! She has a golden finger! Beware of Mary Sue traits! The story is still sweet, sweet, sweet! The male lead's name is listed among the supporting characters. There is some danmei in the story. If that's not your thing, lovely readers, just click X. See you in the next one! Everyone has different tastes. If you really don't like it, just click the X. No need to tell me you're dropping it, thanks! P.S. The story has 70% anti-piracy protection, with a 72-hour delay. Screenshots have been posted on Weibo! Theme: Become a better version of yourself through independence and self-reliance
