On Friday night, none of our usual friends can make it, leaving me alone with my childhood friend Rei for the first time in years. We fall back into our old rhythm, play around until exhausted, and impulsively check into a love hotel rumored to be haunted. I had always seen her as just a friend, but we were drunk, and the hungry look on her face broke my restraint. By morning we have spent the night fucking like crazy. We have simply learned something new about each other—and agree to keep this occasional secret fun from the rest of the group.
