To Survive, Tell the Truth

In a seemingly ordinary game, 7 players have to live on the island for 7 days. They have no dangerous missions or sudden external threats. Logically speaking, the 7 days should have passed safely and smoothly. But the process is always unexpected. Disgust, fear, selfishness, greed... When negative emotions continue to emerge, everyone becomes uncomfortable, and the game becomes abnormal. When the dark side of human nature is completely out of control, can this game still have a peaceful ending?
