[Sweet romance + palace intrigue, not an innocent couple + one-on-one romance later + lighthearted power fantasy + fictional setting, no need to nitpick + hopeless at naming]
Emperor Duan Jingyi of Liang was traveling with Consort Li, Dong Wan'er, when they were ambushed and gravely wounded. By chance, his soul entered the body of a tiny kitten, and he was rescued by Consort Hui, Gu Huiyin. From then on, he stayed by the side of this fierce, pampered consort and saw every shade of life in the harem. Looking back, he realized he had given his heart to the wrong person, while his true love had been right in front of him all along.
Only after becoming a “beast” that anyone in the harem could kick did he truly understand the warmth and coldness of human nature. All that fawning and ardent devotion had been an illusion. Behind the scenes, everyone was up to no good, and even princes and princesses who had yet to learn their letters could instantly become “cat killers.” Life was hard, but fortunately he met a housekeeper who seemed fierce but was kind at heart. Duan Jingyi finally found his true love, and once he regained his human form, he would devote all the tenderness in his heart to her alone.
