Transmigrating as the Cannon-Fodder Stepmother of a Period Novel's Male Lead

Sun Qing woke up to find she had everything everyone else could ever dream of having. She had money, a house, a car, a son, and a cheap husband. Everything was ready-made. She thought she had achieved her happy ending without ever having to work, but who knew she'd transmigrate into a period novel and become the mistress who'd make the male lead cheat before dying just three years into the marriage? Sun Qing: I definitely won't act like a stupid woman. Can't I just focus on making money? She casually got into the renovating business. Her interior designs became wildly successful, and many material suppliers began to approach her with checks so that she would offer them guidance. She'd travel around the lake when she had free time with other rich women. She bought several plots of land there. In less than a month, the market value of those plots of land increased by several hundred times. The rich women all entrusted their wealth to Sun Qing and begged her to invest on their behalf. *** Running multiple businesses and making a lot of money, Sun Qing was so busy that she began to lose patience after waiting a long time. 'Why isn't he here to pick me up yet?' One day, Jiang Hui pressed Sun Qing against the bedroom door. There was a dangerous look in his eyes. "I heard you've been talking behind my back as of late." Sun Qing was slightly terrified. She quickly shook her head. "It wasn't me. I didn't do that. Don't make things up!"
