Takuya Ichijo is an ordinary high school boy who seems to be the picture of mediocrity.
That is Takuya Ichijo.
However, in his class, there is a beautiful girl named Shion Saegusa, who used to be the center of a national idol group and is the opposite of ordinary.
She is always at the center of the class, and even though she has retired, she is still the most popular girl in the school, smiling like an idol and treating everyone with respect.
However, when she appears at the convenience store where Takuya works, she is always acting strange and suspiciously.
