One day, I received a call from my senior asking me to take care of a pet. Awaiting me was a beautiful girl with fair skin and black hair—Matsuoka Miou. However, this 'pet' was not just a playful animal; she herself possessed a mysterious charm that fit the description perfectly. Quiet as she was, we gradually closed the distance between us, eventually leading to a mutual yearning. Amidst various playful scenarios, our overnight cohabitation was filled with excitement and tension, but I couldn't help but notice the photographer's heavy breathing. In this context, the relationship with Miou felt like a dreamy experience. There was an invisible chemical reaction happening between us.
