The male protagonist Li Xiaoyu, named after a girl, is a demon who escaped from a place of confinement. He admired a banshee named Xiao Wei, but Xiao Wei chose a mortal to fall in love with. As a result, he stayed alone in the ice hell for nearly a thousand years. When he woke up, he found that he was still in a place with heavy snow. Xiao Yu was extremely afraid of the cold, and was struck by the cold, but was saved by Xi Nan. After getting along for a long time, Xiaoyu found that this place was more dangerous than the extreme cold, so she wanted to return to her hometown of Yulan Island.
