Raising a Sickly, Clingy Demon King

[Updated, and it's the ending!] Yunjian, a thousand-year-old lingzhi spirit, transmigrated into a book while undergoing a trial, becoming the scheming real daughter and villainess in a modern melodramatic novel. Yunjian: I'm not human. I don't have those messy human feelings. So she walked away and quit, traveling around to sample delicious food, bringing good fortune and wealth to her original family's business, becoming a well-rounded student with good grades and strong character, enjoying a happy modern life, and rescuing a clingy cat spirit beast. The good life lasted until one day, when Yunjian was happily lazing away at university and suddenly heard some explosive gossip. The "husband" she'd abandoned, who was gravely ill, had come all the way from his hometown to find his wife. Yunjian: "???" How could a model lingzhi spirit like her possibly do such a thing? QAQ When she went to find him, the handsome stranger's face was red with fever. Seeing her, he turned away, facing the wall, his eyes damp and full of wounded indignation. "Didn't you already decide you didn't want me? Why come here pretending to care?" Yunjian: "...Could you loosen your tail first?" It's hurting my wrist. She suddenly remembered the "marriage contract" (?) she'd received a while back and tossed straight into the trash. * Branded a cursed loner from birth, cast out of his clan by his parents, and left to wander for centuries, he returned to his lair countless times battered and bruised, licking his wounds alone. After being ambushed and gravely injured, he ended up in the human world... He was aloof, gloomy, withdrawn, infamous, and feared and loathed by others, yet he had never bowed his head to anyone. Until he fell in love for the first time, only to be deceived, used, and abandoned by that woman. I want to destroy the world.jpg #She clearly promised she would only ever love him and never abandon him. #Where did all those sweet words go, the ones she whispered while coaxing him to let her pet his paws and ears? [A possessive, clingy, sickly Demon King x the sweet lingzhi girl who is his natural nemesis] [Modern alternate universe, male lead travels from ancient times to the present, female lead transmigrates into a book, and her constitution naturally attracts all kinds of nonhumans] [Important: This is not an age-gap romance with a younger male lead! He's older than the female lead. He appears in human form at nineteen, so he's an adult.] [Once the male lead fully recovers his powers, both his appearance and personality will change. He'll be an unbelievably handsome beauty.] Everyone, check out my upcoming rebirth story, I Want to Make Him Blush Blurb: Yunkui died at twenty-two, the year a hit drama made her a huge star, famous across the country. That was also the year her first love betrayed and framed her, ruining her reputation. Trapped at a mudslide disaster site, she had both legs crushed, ending her career and turning her into a helpless outcast, abandoned by everyone. A man took her in and raised her in a luxurious mansion, sparing no expense. The man never spoke or showed his face. He never touched her, cherishing her as if she were a priceless treasure. But even with every medical treatment at his disposal, he couldn't stop her life from slowly fading, or revive her heart, which had already withered and died. After Yunkui died, she finally saw the man's true face and discovered the passion and madness hidden beneath his cold exterior. * Yunkui was reborn in her youth, back in the days when they had grown up together. The boy bore the label of a murderer's son. His only family was his blind grandmother. The roof leaked, and drafts blew in from every side. Year after year, he grew quieter, his back slim and straight, his manner cold and indifferent. He kept to himself and cared for no one. Yunkui wanted to repay him, and nothing more. Until a dream, when she was seventeen, suddenly brought back the way the man had looked at her with such restraint in her previous life. Why had she never noticed before how red the boy's ears got when he spoke to her? His breathing grew heavier, his dark eyes deepened, and a fiery blush slowly spread across his pale skin. Ji Chaolin thought it was only a dream, until he saw her approach and give him a shy, closed-lip smile. He was utterly lovestruck and didn't sleep a wink. Later, when his wish finally came true and he tasted the sweetness of the lips he'd longed for day and night, he thought to himself: People risk everything for love, like licking honey from a blade. She gave him just a little of her love, but after tasting it once, he could never let it go for the rest of his life. #I want to lose myself with you in an endless summer, hold your hand beneath the stars, and fall asleep to the night breeze.
