How Do I Deal with Being Reincarnated as the Villainess?

[Going premium on October 31, with a special 10,000-word update. Every lovely reader who comments on Chapter 26 will get a gift!] After transmigrating from an overworked office drone into a beautiful, fair-skinned heiress with long legs, Rong Yan declares, "I want to be a happy little freeloader until the end of my life." But when she learns that she's transmigrated into a book, Rong Yan suddenly gets a terrible feeling!!! When she discovers she's become the vicious supporting female character destined to get killed off, Rong Yan is utterly horrified!!! Uh, Great God of Transmigration, I don't want to be a freeloader anymore. Could you send me back? First, there's a mess left behind by the original owner to deal with. Then there's the big bad villain to appease. Rong Yan: I have a few choice words, but I'm not sure I should say them. P.S. 1. One-on-one romance, both leads are each other's first, sweet romance. 2. Two updates a day after the story goes premium. New story now underway. Please add it to your collection: "The Male Supporting Character Is My Son [Book Transmigration]" Ruan Shishi transmigrates into a book as the mother of the male supporting character, a lovesick man who willingly dies taking a knife for the female lead. Ruan Shishi: ... Everyone knows that the Ruan and Kong families' marriage was a business alliance, and that Kong Zhengqin and Ruan Shishi are a couple in name only. They rarely appear together in public. Once, when people learned that Kong Zhengqin would be attending a banquet with his wife, they all waited for a juicy spectacle. Things went just as they expected: the couple didn't exchange a single word all evening. That is, until someone saw this in the restroom. Kong Zhengqin cornered Ruan Shishi by the restroom door. His usually stern face showed a hint of grievance as he murmured, "Honey, I've been sleeping in the study for three days." When word of this got around, the gossip group moderator was speechless. "A couple in name only, my foot." Theme:
