You Can't Look Back with the Monument Behind You

I received a red paper letter from my "grandpa" in my hometown, asking me to return to my hometown to attend his funeral. The ceremony must be held in the early morning. When meeting, you are not allowed to ask about the life and death of relatives and friends, and you are not allowed to cry when expressing condolences. On the night of the vigil, I found that the tombstone behind my photo had different causes of death engraved on it: drowning, hanging, and dismemberment. Every time one is erased, one person disappears from the village. When only the word "burn the corpse" was left, the whole village of paper figures surrounded my house, beating gongs and drums: "The time has come, please go on your way -" - I must survive in this weird funeral prepared for myself, and find out the bloody truth hidden behind the rules.
