I confessed to a pure girl back then. I was rejected and was feeling down for a few years. Suddenly, a friend from back then contacted me and told me that one of their classmates was working as a call girl. I was curious to know who it was, but I thought it would be fun, so I called her and she turned out to be a pure girl! I don't know if it was revenge for that day or just a perverted Kokoro, but I called her anyway.
