If there’s one thing that’s not ordinary about my high school, it is the presence of Shion Saegusa, my classmate. That’s because she used to be the center of a once nationally famous idol group. She’s always at the center of the class, and even after her retirement, she still interacts with everyone with a smile and cheerful demeanor like an idol, making her the most popular person in the school. However, whenever she visits the convenience store where I work part-time, she acts suspiciously and behaves oddly for some reason. Wearing a mask, large-framed glasses, and a cap pulled low over her eyes—she might think she’s in disguise, but if we’re facing each other across the counter, it’s pretty obvious that she’s my classmate, Shion Saegusa. I’m not sure what she’s trying to achieve, but as usual—my former idol classmate is behaving suspiciously today.
