My dream is to go to college in Tokyo. Airi said she'd be back in the summer, so I promised to drive her there. On our one-year anniversary, I asked her about her future goals. As her boyfriend, it was my duty to support her. Even though I was worried, I had no choice but to send her off. I never imagined that the girl I trusted would be consumed by a world I didn't know about just a few months later, indulging in shameless pleasure. This is Airi Nagisa's first attempt at a hardcore NTR drama.
