Cage Game

When I woke up, there was only a bed, a bedside table, and a door in the room. There is a piece of paper on the bedside table: "Say the rules and you're gone." I found the first rule: no lying. Then I met her. The rule she found was: no telling the truth. Which of us is lying? —— Seven people, seven rules, seven erased memories. The rules are contradictory and the penalties are progressively higher. Someone died. Someone is crying. Someone had no intention of letting us out alive from the beginning.
