Upon her rebirth, Yun Shifei reclaimed her fifteen-year-old life, discovering she had become the legitimate daughter of a prestigious family. Timid and obedient, Shi Fei yearned for nothing more than a quiet, peaceful existence. Then she crossed paths with the Great Demon King. According to her past knowledge, this formidable being was merciless—he wasted his family's wealth without remorse, remained unmoved by his brother's death, and orchestrated his father's imprisonment. Yet the man before her is gentler than expected, docile, defenseless, and perpetually drawn to her side. Yun Shifei's defenses crumbled as she devoted herself to shielding him from harm. Until the moment her vulnerable companion pulled her close and sealed her lips with a kiss. She froze, mind reeling. With feigned innocence, he whispered: 'I learned this gesture conveys affection. Don't you harbor feelings for me?' The words held logic, yet something felt dangerously amiss.
