``Tsukasa'' was a mysterious woman who seemed to have no desires and always seemed to be missing something. I was attracted to her and started dating her, and I thought we were living a happy life together... One day, I was leaving the house we were living in together, so I decided to take some sneaky shots with my camera. What was reflected there... I brought my middle school male teacher, who is a year older than me, into my house and taught him from morning till night.
