"Mother," I opened my eyes. Everything around me is a haze. I gazed at the candlelight. It was wobbling from side to side. I noticed a woman seated near me, but everything was fuzzy. I heard a voice unexpectedly. It was a woman's voice, echoing in my ear. She was singing a low-toned lullaby. "Mother, is it you?" I heard my name, "Maxilin, I am here." "Mother," I said with a tremble in my voice. I have no idea what's wrong with me. I reached out cautiously to touch her, but she was out of my reach. "Where are you, mother?" "Oh, my beloved, try to hold me, come here, " "Mother," Maxilin tried to stand up, but he was too weak. Maxi narrowed his eyes in an effort to see her face clearly, but he couldn't because everything was fuzzy. A woman in a white outfit moved in front of his sight. Maxi took a few steps forward while still gripping the chair. "Mother, don't leave," he murmured, dizzily. As he said, he saw in his fuzzy vision that someone had opened the door. "Mother, please don't leave me," Maxilin pleaded. He let go of the chair's hold and dashed behind her. "Mother, don't leave me. Wait." In his frail state, he shouted and followed her. "Huf". In the middle of his path, he stopped. "Mother, you've left me here alone," "Maxi," he heard the voice unexpectedly. Maxi glanced up and looked around. It's all clear now, but he's stuck in the midst of the woods. He gazed up at the sky. A giant moon was staring at him, and a horde of deadly, voracious creatures were roaring around him. "Son," someone touched his shoulder, he looked back, saw a terrifying creature standing in front of him. "Hello, dear."
