There were people who could get into the brain of others and manipulate their memories.
Their power was used to erase murders and other illegal incidents that happened in the underground.
While they destroy the spirit of other men, they also corrupt their own hearts. They get chained up to keep the fragile and dangerous heart safe. Because they were feared, they were called ‘pet.’
