The protagonist is a third-year high school student, and his sister, Ai Shichijo, is a second-year high school student. Ai has maintained her position as the top student in her grade since she entered school. With her glossy long black hair, silver-rimmed glasses, and calm blue eyes, she is a well-known honor student at school. Calm and polite, she is seen by those around her as a "perfect girl."

However, in front of the protagonist, her family, she is a little different from how she is at school. She cheerfully talks about her thoughts on books she has read, tells him about things that happened at school, and sometimes teases him with small pranks or jokes. Even Ai, who seems perfect, has worries, weaknesses, and times when she can't be honest.

Reading books in the library after school, walking home together, studying at home, going to the bookstore on holidays. As they accumulate these ordinary moments, the distance and trust between them gradually change.

This is a story about getting to know the real Ai, not the honor student, but the face she shows in front of her family. It depicts a warm, youthful daily life spent between siblings, cherishing everyday conversations and small memories rather than special events.
