The book, Mysterious Immortal: The Useless Prince's Indiscriminate Pet of Cats, might meet your needs. The female protagonist was dressed as a man, cold, overbearing, cool, and arrogant. The male protagonist's identity was undisclosed. He was a loyal dog who spoke but meant nothing. His loyalty was to dote on each other. In the storyline, the useless Prince had a reverse scale and could not touch his cat. The Crown Prince loved to pamper his cat until the cat climbed onto his head and asked," Are you happy?" He pampered the cat until it climbed onto his father's head and asked the cat," Are you happy?" He pampered the cat until it climbed onto everyone's head. His Highness the Crown Prince smiled." Are you happy now?" I hope you like my recommendation.
