Sano Taichi became friends with Hiiragi Kana after getting a part-time job as a shooting assistant. Taichi thought Kana was pure, but she turned out to be a girl who was very interested in erotic things. The two of them ended up shooting an image video that paid more than their part-time jobs. Taichi wasn't enthusiastic about it, but Kana was all set, even writing the script. On the day, while shooting, Taichi started to feel like he was actually on a date, but at the same time, he had mixed feelings about the fact that she wasn't really his girlfriend. Unaware of his feelings, Kana's next destination was a love hotel. Ignoring Taichi's bewilderment, Kana put on a swimsuit, prepared a mat and lotion, and began setting up for the shoot.
