The Supporting Female Character's Er Gou [Book Transmigration]

This is a story about a "transmigrated book character" and a "dog of a male lead." (The heroine transmigrates into a book, and the hero transmigrates into a dog's body.) Gu Nian wakes up to find herself in the book as the male lead's tragic fiancee, a vicious supporting character who is always making a scene to get attention. Live for the male lead, die for the male lead? Not a chance. I've got money to spend, a dog to pet, and a luxury car and mansion. Why would I risk everything when I've got what everyone else can only dream of? * After Lin Jinyuan is in a car accident and becomes a vegetable, Gu Nian takes devoted care of him and loses more than ten pounds in just half a month. Everyone thinks Gu Nian is deeply devoted and madly in love with Lin Jinyuan. Even when the doctors say the only hope is a miracle that might wake Lin Jinyuan, she still refuses to leave him. Only Lin Jinyuan knows that this woman says one thing and means another. She's deceitful and downright hateful. Every day, she cuddles his dog and mutters about breaking off her engagement to him so they can go their separate ways and she can live a carefree life. When Lin Jinyuan wakes up, he sees Gu Nian coming to call off their engagement and gives her a sinister smile. "We haven't settled our account yet, and you think you can run? Not a chance!" P.S. One-on-one romance, both leads have had no prior partners, and the hero will regain his human body. Extra sweet! Theme: Though the heroine transmigrates into a supporting character, she is determined to escape her fate and become the protagonist of her own life instead of playing second fiddle to someone else.
