I Transmigrated into a Book and Picked Up a Dog. He’s a Trillion-Yuan Demon King

[Transmigrate into a book + financial tycoons + aristocratic academy + sweet romance + contrasting charm + demon clan + double identities + devoted to each other] Su Ruan transmigrates into the book as a cannon-fodder female character, and from the start the scheming heroine gives her a red card and orders her out! To stay alive, she picks up a dying little white dog on a stormy night, forces it to take a bath, rubs its belly, and feeds it ham sausage. Who could have guessed that this haughty little dog is actually the Snow Wolf King, the strongest fighter in the demon realm, and also Huo Ye, the trillionaire heir to a financial empire?! By day, he's 192 centimeters tall, with golden eyes and silver hair. As the leader of Saint Sia's F4, a single word from him can make the whole academy tremble. By night, he shrinks into a palm-sized puppy, whimpering in her arms for a piece of ham sausage, and stubbornly covering his crotch so she can't bathe him! Even more unbelievable, Su Ruan's palm can glow, and a single touch can heal his wounds. The mighty Demon King is gravely wounded and on the verge of death, but her unconscious purification saves him. From then on, he clings to her! The scheming heroine sets her up? The tycoon tears a door off its hinges from across the room, and all four tires on a supercar explode! The original male lead looks down on her? The Demon King's phantom form crushes everyone on the spot! Su Ruan thinks she's raising a little snail-dog, until one day a naked man with spectacular abs appears in the bathroom and pins her against the wall. His silver wolf tail winds around her waist. “Ruanruan, don't look at other dogs. From now on, I'm the only one you can touch.” From cannon fodder to Demon Queen, from poor student to real heiress, Su Ruan smiles and pinches his wolf ears. “Huo Ye, are you going to be my dog or my man?” Huo Ye grits his teeth. “Both.”
