All stories begin with a family of ghost hunters...
Speaking of this generation, a girl from the Tong family gave birth to a pair of twins. Although the marriage of the girl from the Tong family did not have the support of the Tong family, it was something worthy of celebration. However, the palmistry of the twins completely surprised them - in that pair of twins, the boy defeated his wife and the girl defeated her husband.
Despite this, the little life was still happy. At least that was true before the Tong girl and the child's father had a car accident.
When a girl from the Tong family got into a car accident, the twins were dubbed "parent-killers". Only their aunt volunteered to take care of them.
The tradition of the Tong family is to start learning to hunt ghosts at the age of sixteen. What changes will the twins' sixteenth birthdays bring to their lives?
