Born in ancient times, Gou Dai, the ancestor of the Demon Clan, picked up Mu Yuan when he was lost and kept him by her side out of curiosity. Later, Mu Yuan went to private school and Gou Dai fell into a deep sleep. After ten years of separation, Mu Yuan slipped back to the Demon Clan to find Gou Dai.
Gou Dai and Mu Yuan came to the mortal world. At this time, Mu Yuan had won the first prize and gave up being an official. In the name of studying, the two traveled around the mountains and rivers. Mu Yuan gradually understood his feelings for Gou Dai, but he never dared to say it out. He thought that he was a mortal and his life span of only a hundred years was too short for Gou Dai. He did not want to cause trouble to her. Gou Dai loved Mu Yuan very much, but she had never experienced love. She only thought that her feelings for Mu Yuan were just like when he was a child.
During this period, the two experienced a lot, and there was a lot of warmth and sweetness, which made Mu Yuan sink deeper and deeper into the world and couldn't extricate himself.
