Ten years ago, their brother left for no apparent reason, and the two sisters went to a remote orphanage. The dean's wife there was very weird and refused to let them have anything to do with their brother's disappearance and things that happened before they were 6 years old. She has been forcing their memories.
Something happened when they were 16 years old, and they were sent to the academy. It was full of evil energy, and the two originally pure sisters were devoured little by little. When the mist gradually revealed clear shadows, I discovered that my brother once studied in this college. Everything becomes more suspenseful. The fog is thick, when will the grudges end?
