As an intern cat demon, Shi Miao is on a mission to transmigrate into a book and save Jiang Yingxu, the villain who derailed from the plot and was destined to be abandoned by everyone and die miserably on a winter night. She squats on the wall, seeing his pair of dark eyes desolate and devoid of light. "Don't be afraid, your cat king is here!" Since then, Shi Miao disguises herself as a transfer student by day to accompany him, and transforms into a calico cat at night to snuggle in his arms. Feeding him, shielding him, and swatting away everyone who bullies him with a single paw, she vows to pull him out of his blackened ending. But the closer she gets to the truth, the more she realizes this cross-time encounter was never a coincidence. Who would have thought that I, a little cat, accidentally raised the paranoid villain into a husband? "You are the delusion with which I quench my thirst with poison" — Jiang Yingxu
