Transmigrated into the Little Fairy of a Powerful Tycoon

[Blurb] After waking up one morning, Su Keke was shocked to discover that she had transmigrated into a Mary Sue novel about a heroine rising to power. Just as she was agonizing over whether to use her transmigrator's halo to go head-to-head with the Mary Sue heroine, she realized she had possessed... a winged fairy doll belonging to the story's biggest villain! That same night, a meteor streaked across the sky, and the dark villain Ling Yichen watched in disbelief as the fairy doll he'd kept by his side since childhood miraculously came to life in a burst of starlight! His voice was low and full of suspicion as he pinched one of her little wings, threatening her. "What are you? Where did you come from?" Su Keke (trembling): "I... I know you might not believe this, but I... I'm a fairy godmother sent by the gods to purify you." Ling Yichen: "????" Ling Yichen had suffered a great deal in his life. His father didn't care for him, and his mother didn't love him. With a sheer determination to work hard and risk everything, he had built an enormous business empire all by himself. The outside world always said he was ruthless, cruel, and violent, but no one knew that was just a hard shell he used to protect himself. He longed for family and love, but nobody understood him. They were so afraid of him that they didn't even dare look at him for long. Only this sudden newcomer wasn't afraid of him. She liked to nestle in the palm of his hand and softly act cute. She stayed by his side when he was sad, and when he was sick, she would struggle to hold her little cup and feed him water, making sure he took his medicine. She was the little fairy in his palm, his treasure, a ray of light that rescued him from loneliness and darkness. He was willing to give her the best things in the world.
