I, Sato Jubei, am a high-spec but slightly shy, introverted loner with social anxiety, a second-year high school student. I have zero friends, but a turning point came into my life. I get confessed to by Kurogami Nene, the school idol who has all the boys in the same class smitten. However, it was a fake confession, so I politely declined. That was the catalyst for learning about the hidden side of the idol, and I ended up being followed around by Kurogami Nene.
