Intro

The school building after hours gradually becomes lively with the footsteps and laughter of students heading to club activities. However, in the library at the back of the second floor, a quiet time flows, unchanged as always. The evening light streams through the large windows, dyeing the bookshelves and desks a pale orange. Sitting in that window seat is a high school sophomore and library committee member—Ai Shichijo. Turning the pages of a book as her long black hair sways slowly, she was a model student known to everyone at school. Top grades in her year. Refined features. A composed demeanor. Polite to everyone, always calm. A girl who seemed to handle everything perfectly. However— In front of you, her family, she is a little different.
