There is a large manor in a small town. The manor is very large but there are few people coming in and out. What you often see is a smiling young man. Occasionally, his maid in black dress will appear. No matter how beautiful the jade is, there are flaws. The maid in black dress who comes in and out of the manor seems to have an injury on her left eye. What is the reason? Why did people in the town die for unknown reasons?
