Lan Yue, a college student, has a sick father to take care of, so she works several jobs to make ends meet and pay for medicine.
Unexpectedly, my father got better one night, but an unexplained murder occurred in the neighborhood.
A mysterious and cold beautiful young man Bing appeared in front of her, but he took away his father's soul.
Later, Lan Yue, who was sent to the supernatural police force for further testing because of her special abilities during a physical examination, learned that the Soul Educators were a special branch of the supernatural police force. What they hunt are those demonized souls that still linger in this world after death.
Lan Yue and Bing seem to keep meeting each other due to fate.
His partners, Xuanyuan and Lan Yue, who are as bright as the moon and breeze, love each other, but Xuanyuan is actually Lan Yue's half-relative.
The beautiful and lovely brother Abe whom Lan Yue picked up during her mission is actually a poisonous Mido shell fairy.
Their entangled fates involved them in several strange events.
Finally one day, Bing's prey became Lan Yue.
