Strange Tales of Rules: Survival in Snow Mansion

From the moment we step into the mansion, we become prisoners kidnapped by memory. The bell is a curse that urges death. Every time it rings, a layer of truth is torn apart: the disappeared person did not disappear out of thin air, but fell into a twisted "other world"; what seems like an accidental encounter is actually a plot carefully laid out by various forces; even those tampered memories hide the fate passed down by the family. The three parties are wrestling in the dark, and the secrets of the mansion are locked up. In the process of looking for a way out, we are forced into desperate situations by the sound of the bell again and again. It is not until the fifth bell rings that we finally see the cruel truth: we are not here to solve the mystery, but to complete a sacrifice that has been destined for a long time.
