A three-story Gothic hotel stands in the misty forest. In the deep night, warm orange light shines from the hotel windows. A wooden signboard with "Moon Shadow Hotel" written on it hanging at the door has a moon pattern on it. A 23-year-old black-haired Chinese youth stood at the door, wearing a black vest and white shirt, with a helpless smile on his expression. Several mysterious figures could be seen vaguely behind him: a silver-haired butler, a red-eyed girl, and a tall werewolf. The overall atmosphere is mysterious and warm, with warm light in dark tones and a fantasy style.
