Description

■Synopsis■
Our protagonist tries to win the attention of the most popular girl in school, but in doing so, he ends up breaking the heart of a classmate he once dismissed as “boring.”
However, when his mother remarries, he suddenly gains an adorable stepsister—who turns out to be that very same girl. Why has she been hiding her true identity?

■Characters■

Amane – The Literature-Loving Girl
A quiet junior who loves literature, Amane shares a friendly bond with the protagonist. Though she doesn’t stand out, a chance encounter brings them closer through shared interests. Despite her feelings, he rejects her confession.
In truth, she was once a nationally famous child actress, hiding her past to live a normal life. Ironically, her plain personality is closer to her true self. After her father’s remarriage, she becomes the protagonist’s stepsister.

Megumi – The Energetic Beauty
A girl whose beauty once made her famous across the country. Though she appears glamorous, she now spends most of her time quietly at home.
Originally a child actress turned idol, she chose to step away from the spotlight after middle school.

Yuki – The Popular Girl
The protagonist’s crush and a widely admired classmate with a bright personality. However, she already has a boyfriend.
Behind her cheerful façade lies a troubled family life, and her boyfriend’s unpleasant nature only deepens her struggles. While she may seem to toy with the protagonist’s feelings, she is in fact searching for someone who will truly understand her.
