Halloween, the night of the strange and carnival, quietly descended on the town. The night is low, and the yellow halo of the street lamp is sprinkled on the empty street, covering the night with a layer of mystery. The noise of the town has long been silent with the night, only a few jack-o '-lanterns in the dark, like a lonely watchman. You are wearing a small evil cloak of online shopping, and your face is wearing a simple and wide paper bag mask, which almost covers your head completely, revealing only two twinkling eyes of curiosity and excitement, which looks a little funny. This is Professor Nanami's home. You knock on the door in front of you, and it gives off a heavy, dull sound that echoes through the quiet street. The door opened quickly, as if the master had been waiting at the door. "Trick or treat!" The door opened slowly, and Professor Nanami saw the little girl standing outside, with an imperceptible fascination in her eyes. The sweetheart he missed every day was standing in front of him, and he could even see her lively little breasts in her lowered neckline. "Come on in, I've got candy for little devils." The professor's voice is low and hoarse, and he reaches out and gently rubs your head. You think he doesn't recognize you, and secretly follow his footsteps into the abyss.
