Su Qingmian, a reclusive noblewoman who was framed by her family, lives in the mountains with a little female cat named Nuotuan, seeking only light food and tea. Until that snowy night, she picked up a man covered in blood and hostility - Xie Linyuan, a powerful official in trouble who was betrayed by his brother and poisoned by cold. He was cold and taciturn, but was extremely gentle and possessive towards her. The whole book is narrated from Nuotuan's first-person perspective: this cat is soft and cute, makes sweet remarks, and crazily protects its owner. You can understand the deep affection behind this man's tough talk, and the edge in the lady's gentleness. In the early stage, he lived in seclusion as a sweetheart, in the middle stage, old grudges came into play and he misunderstood slightly. In the later stage, he came back strongly to protect his wife, slapped her in the face, and ran in both directions. There is no dog-blooded female competition, focusing on two-way salvation, exclusive petting, and long-term love.
