The lonely inner island, closed and dark. A ray of warm sunshine is like a drop of water in the desert, giving people infinite desire. She walked in betrayal, helplessness, guilt, and loss. Behind the momentary hope was endless despair and biting cold. Then abandon everything, bear all the pain, and go against the world. Divide the earth into a circle, isolate yourself from the world, and lose your original intention. Hidden in the darkness, the sharp knife has been put to the throat, risking one's life, who will live or die this time.
