The Idle Beauty Volunteers for a Marriage (After Transmigrating Into a Book)

Blurb: Yan Shuangyi transmigrates into a book, becoming a cannon-fodder character who shares his name. Unlike other cannon-fodder characters, who either recklessly compete with the protagonist for a love interest or bully the protagonist, eventually driving them to become a villain, he is a true cannon-fodder: he has absolutely no part in the story. The protagonist of the book is the male lead, Jiufang Yan, and his twin sister, Yan Shuangshuang. In the original story, Yan Shuangshuang is renowned throughout the capital for her beauty, but she is spoiled and willful. Having already pledged herself to her lover, she resents the marriage arranged by her parents and puts a green hat on Jiufang Yan's head. As if that weren't bad enough, the man she loves is a scumbag who intends to use her to bring down the male lead, Jiufang Yan. In the end, the entire Yan family is executed, including Yan Shuangyi, the cannon-fodder character with no part in the story. When Yan Shuangyi arrives, he sees his sister refusing to put on her wedding clothes, even if it means dying. Several servants have been ordered to bring her a drug that will knock her out so they can carry her to the bridal sedan. Looking at his face, which is ninety percent identical to his sister's, Yan Shuangyi comes up with a plan. He stops the servant, takes the drug into the room himself, puts on the veil, and takes his sister's place in the bridal sedan. So what if he's getting married! Yan Shuangshuang can't let go of the man she loves, but Yan Shuangyi knows better: Nothing matters more than staying alive. Besides, he finished reading the novel, and it was strictly no-couple. Jiufang Yan, the only overpowered male lead in the whole book, is famously devoted to his career, a relentless workaholic. He has no interest in love and keeps his distance from women. He never lays a finger on Yan Shuangshuang from beginning to end, and probably can't even remember what her face looks like. Of course, he won't notice that his wife is a "fake." While making diligent efforts to help his sister see the scumbag for what he is, Yan Shuangyi plays the part of a gorgeous ornament in the Feng family's inner courtyard. His guiding principle is not to get in the way of the overpowered male lead. The Yan family is wealthy and influential, after all. As long as he behaves himself, sooner or later he can get a divorce decree and be free to roam the wide world! But why has the supposedly "uninterested in women" King of Hell been showing up in front of him every day lately? And why is he looking at him so strangely...? Yan Shuangyi has a bad feeling about this. He packs his belongings and gets ready to run, only to turn around and find Jiufang Yan has caught him red-handed. He does his best to speak in a high, delicate voice. "Um... would you hear me out while I make excuses? No, wait! Explain!" Jiufang Yan gives a cold laugh and backs him up against the wall, his low voice still irresistibly sexy. "Then start by speaking normally." Warnings: 1. Both are virgins, one-on-one, happy ending. It's more or less a marriage-first, love-later story. The love interest and the protagonist's sister had nothing to do with each other in the first place. 2. The sister isn't a bad person either. At most, she's a rebel against feudal etiquette and its victim. But with the protagonist's arrival and "self-sacrifice," everything will change. Blurb published on 2021/9/7 Theme: Saving each other
