An old single room in Hangzhou rented for RMB 300 per month has an indelible dark brown handprint on the wall. Desperate, I signed a rental contract, not knowing that this was a hunting game of centuries-old resentment. The handprints move to the left every night, the heartbeat is hidden in the wall, and the same brand is burned on the chest. System warning: If the handprint is aligned with the heart, I will be permanently assimilated.
