The arrogant and cold Yu Xingji, the leader of the Twelve constellation deities, traded his memories in exchange for reincarnating a thousand times in order to find his true love. During his 1001st reincarnation, he's reborn into the life of a college professor, where he meets Qin Ling, an aloof young man in possession of strange spiritual powers. When a strange event suddenly happens on the school campus, Yu Xingji couldn’t help but find himself standing in front of Qin Ling to protect him during the most critical moment! While the relentless reincarnation cycles may have erased the memories and appearance of his lover, only the emotions carved in his bones and engraved in the heart will guide them to reunite once again.
