The world is one giant sheep pasture.
Each of us is a lamb to be slaughtered.
Yu Zhi's sister disappeared, and Yu Zhi found a strange sheep-head mask in her sister's room.
Her world has never been the same.
Disappearing corpses, bleeding photo albums, wardrobes that make noise every night, drawers that cannot be opened, people who follow you home late at night, perverted murderers that only you can see in the subway...
Countless weird stories appear in the city. Can she survive each incident?
Purpose: I hope you can always be free, strong, and fearless.
