A young woman from a certain place had been accepted into a university in Tokyo and was planning to live alone in the city. She began her life in a Tokyo apartment and unexpectedly discovered a small hole in the wall. This small opening seemed to look into the neighboring room, so she decided to take a peek. On the other side of the hole, she saw a deep red color. She wondered if the room next door was covered in red posters, and with this thought in mind, the female university student continued to peek through the hole each day.
No matter how she looked, it was always just red. She couldn't help but become increasingly curious about the room next door, so she decided to ask the apartment's landlord. She inquired, "What kind of person lives in the room next to mine?" The landlord replied, "The person in the room next to yours has an eye infection."
