an angel who was held by a dirty man

The man in the dirty work clothes was a cleaner at the apartment where Miyu lives. Even though they usually met each other, they were "invisible people" for the residents' miyu. The man told me about it, and I realized it for the first time. And I was ashamed of myself. Because Miyu has also been left out of friends as an invisible being since adolescence. A strange and dense day with a suddenly assaulted, raging miyu and a dirty middle-aged man was about to start.
