After Forcing a Marriage to the Black Moonlight, I Regretted It

Blurb: Lin Yu transmigrates into a book as the eldest daughter of an immensely wealthy family. Her parents dote on her, her younger brother adores her, and she lives a life of luxury. On an outing beyond the city, she comes across an injured young man on the road. When he wakes, the young man introduces himself as Lu Chaoxue. Gentle and serene, refined and elegant, he's exactly her type. Lin Yu wants to get closer to him, so she takes every opportunity to fuss over him. Unfortunately, although Lu Chaoxue seems gentle, he's difficult to approach. All she can do is tell herself to take it slow. Who would have thought he would treat her cousin Tang Mengqing, who comes to visit, with special regard? Lin Yu, who has always been at odds with her hypocritically kind cousin, is naturally furious. To win Lu Chaoxue, she schemes to make him marry into her family. Their married life has its ups and downs, but she thinks she'll get used to it eventually. Then, after accidentally drinking a cup of poisoned tea, she discovers that she has transmigrated into a book, and that the seemingly carefree Lu Chaoxue is actually the scheming, unscrupulous Prince Jiayuan, the story's great villain. Only then does Lin Yu realize that she didn't drink the poisoned tea by mistake: he was trying to kill her. She tries every trick she can think of, but they all fail. In the end, she can only pretend to be gentle and bring him and her cousin together. Everything goes smoothly. But just as she gets a divorce letter ready for him, he tears it up. He looks at her, his eyes red. That's the day Lin Yu realizes he's a madman. Lu Chaoxue: Only after Lin Yu accidentally drinks the poisoned tea does he realize how much he cares about her. All this time, he never noticed the overwhelming love he felt. Because of her, his reason crumbles, and he has gained a weakness. Afraid of frightening her, he acts cold and hopes she'll love him more, until she can never leave him. When she smiles and hands him the divorce letter, he finally understands that she doesn't love him. Fine. He doesn't need to keep pretending, either. Reader's guide: 1. A pampered, domineering heiress and a gentle, white-moonlight type who is also a calculating yandere. 2. The male lead only loves the female lead from beginning to end. He's very good at pretending to be someone he's not. 3. I'll add more if I think of anything. Theme: Live as yourself and enjoy life.
