Book Transmigration: Hurry and Pick Up the Sickly Villain's Fragile Heart

【No System, transmigrates into a book, happy ending, doting romance, sweet relationship between the leads. Warning: the plot gets a little angsty!】 【Timid but fierce girl who transmigrates into a book × gloomy, lovesick villain with a fragile heart】 Xia Yichu accidentally transmigrates into the role of a wicked female cannon fodder who is about to be killed. Xia Yichu: “Whatever. I'll handle it.” Xia Yichu plans to rely on her own abilities to survive to the end. She absolutely will not listen to her mother and cling to the villain for protection! Later, she has to admit the villain really does have his good points. Haha. The first time she meets the villain, he asks with interest, “Why do you keep staring at me?” Xia Yichu: “...You're good-looking.” The second time, the villain says impatiently, “The last thing I need is a friend.” Xia Yichu: “Oh, you're so cool.” Xia Yichu asks, confused and puzzled, “Everyone needs friends.” (She's pretending.) Later, the villain prepares to set off for the northern frontier, raising an army because she told him, “Why not join the military and earn some glory? Then people won't fear you anymore. They'll look up to you and admire you.” Day by day, the villain becomes more and more peculiar. Xia Yichu stares helplessly at the chains and the handsome face right in front of her, perplexed. “Aren't you supposed to be so cool? What are you doing?” But the villain only sobs hoarsely, his expression pained. “Chuchu, be good. Stay with me, all right?” Xia Yichu: “All right, all right. Big Sister is here. Don't cry. Come give me a kiss.”
