After the Villainess Starts Shipping Couples

[Blurb] As a three-time Golden Rooster Award-winning actress and the sole heir to the Jiang family, Jiang Xin has had a smooth life since childhood. Her family arranged for her to be engaged to Gu Qin, and to fulfill her duties as his fiancee, she'd step in and clear away any women who seemed to be getting close to him. One day, Jiang Xin had a dream about a book that told the love story of a man and a woman. The heroine had a tragic past. Orphaned as a child, she had her family property seized by cruel relatives. At just ten years old, she bravely learned to look after herself. Later, she found a little boy and, forgetting that she was still a child herself, did everything she could to care for him and pay for his education. Naturally, this boy was the hero. A few years later, his family took him back and cut off all contact with the heroine. They met again only after he became a famous movie star. Jiang Xin was moved to tears by the heroine, who was like a little angel, and desperately hoped the hero would dote on her and make up for all the hardships she'd suffered as a child. Then Jiang Xin woke up and realized the hero was her fiance, Gu Qin, the little angel was the woman she'd been bullying all along, and she herself was the very definition of the wicked female supporting character. Jiang Xin: "…" Could time turn back? I want to take back everything I've done. Turning back time wasn't an option, so from then on Jiang Xin mended her ways and became the number one fan of Xia Feifei and Gu Qin as a couple. Anyone standing in the way of my ship has to be eliminated! Wicked cannon-fodder girl: Girl, I know you want to stand up for me, but I don't need that anymore. You wouldn't understand how fun shipping them is. Nobody gets to bully my little angel. Devoted second male lead: Jiang Xin patted him on the shoulder. Brother, there are plenty of fish in the sea. Xia Feifei will never be yours, so take the next left and move on! Uncle Gu Qin: I hear you won't let Gu Qin break off our engagement? Draw your sword! You aren't leaving until you agree! A story about a wicked female supporting character who ships the hero and heroine, dotes on them like they're her own children, and ends up happily ever after with the hero's perpetually single uncle.
