It's been five years since I last met Ruri. I met her seven years ago, and though it was a short time, we had an affair. Her husband was an elite man, but he wasn't very good at sex, so she was physically dissatisfied. However, that relationship suddenly came to an end. Her husband was posted overseas, and she decided to go with him. Then, five years later, she contacted me to say that she had returned to Japan. I called her to the park where we always met.
