A high school student + half (pseudo?) Fangirl, traveled through time.
Her enemies had to hide, but they still had to live their lives. She never thought about hiding her name, and at least living comfortably, that's what she thought.
A bunch of strangers, they think they are good, but they are all bad, they think they are bad, but they are actually very good. For a half-year-old girl who once only cared about the amount of pocket money and the eyes of the boys in the next class, it is difficult to distinguish these.
Come and go in a hurry, knowing you have to leave, but still want to stay.
