The fox demon Su Ruanruan, in order to cultivate her ninth tail, listened to the little mouse girl's saying that "finding true love is the shortcut" and happily went down the mountain. This seemingly innocent journey to find love unexpectedly opened up the dust-laden past.
First, they met the gentle He Yunqi and the enthusiastic Xiao Luofeng. Their first encounter two hundred years ago had already laid the foundation for today's bond; then they met the cold Ye Hanchuan, and an intersection seven hundred years ago also surfaced.
What shocked Su Ruoruan even more was that she gradually discovered that she would go down the mountain every hundred years, but her memory would always be erased before leaving. He Yunqi has been deeply in love since they first met and has been waiting for her silently for hundreds of years; Xiao Luofeng's initial admiration also quietly turned into affection during the reunion.
As the memory fragments were pieced together, Su Ruanruan had to go with these monsters who each had their own secrets. On the way to explore "true love", she not only has to face the increasingly complex emotions in her heart, but also step by step uncovers the truth about the memory that is erased every hundred years, as well as the unspoken affection, forbearance and unknown secrets behind this fetter that spans hundreds of years.
