Xuannu followed the Immortal Venerable Chongwen for three hundred years, only to receive reprimands and misunderstandings in return. Disillusioned, she was banished to the Demon Realm, but unexpectedly stumbled into the tenderness of the Demon Lord Yeyuan, who understood her nature, cherished her grievances, and gave her the best pampering in the world. From a despised and mischievous little cat to Suixuan, held in the palm of his hand, she finally understood that true love never needs deliberate pleasing. Learning the truth, Chongwen regretted it for the rest of his life, but could never call back that little cat whose heart and eyes had once been full of him only. In the end, Suixuan and the Demon Lord joined hands to roam the three realms, living a carefree and happy life.
