After I Transmigrate into a Book, I Make the Cold, Stern Scholar Pout

The title is wrong, and I can't change it back, ahhh!!! 【Transmigrate into a book + marriage first, love later + business and prosperity】 Lu Yunshu transmigrated into an old-fashioned tragedy, becoming the villainess who stood in the way of the leads' romance! The first day after she transmigrated into the book was her wedding day. The man she was marrying was Xu Mingyuan, a minor male character whom she drove mad after their marriage and who eventually strangled her to death! Just thinking about such a terrible fate made Lu Yunshu feel awful… But the original owner had brought it on herself. If she hadn't been so blinded by love and gone after the male lead, she wouldn't have met such an end. But the male lead wasn't a good person either. The heroine, Lu Yunqi, was also blinded by love for him, and as a result, the entire Lu family eventually perished in a sea of flames… Knowing that the Lu family would be wiped out, Lu Yunshu tried every way she could to keep the leads apart. As it happened, the heroine had been reborn! This was just the help she needed! After being reborn, the heroine became disgusted with the male lead. Lu Yunshu seized the opportunity to bring her together with her loyal second male lead. But the troublesome male lead kept pursuing the heroine. So Lu Yunshu once again schemed to get him away from her. As Lu Yunshu spent more and more time with the male lead in her efforts to drive him out of the Lu household, she began to upset her nominal husband, Xu Mingyuan. “Do you care that much about what happens to him?” “Of course I do!” Of course Lu Yunshu cared about him! As long as he didn't leave the heroine, she couldn't eat or sleep. Wait, what?! Why was Xu Mingyuan grabbing her by the neck?! Was he going to strangle her to death again?
