This work is a human/immoral drama centered on two sisters—a perfect older sister with good looks and grades, and a younger sister constantly compared to her.

- Synopsis: A Quiet Reversal Story of Comparing Sisters

Older sister Kaho (played by Kaho Yamada) is praised at home and school for her perfect appearance and grades. Meanwhile, younger sister Minon (played by Minon Yajima) has grown up being compared to her sister and insulted as 'ugly and stupid.' Having been labeled in every social circle, the sisters harbor secret pains.

Minon loses her sense of self-worth but deep down wishes to be like her sister. Meanwhile, Kaho, who is admired by others, is quietly cornered by the pressure to remain 'perfect.' Eventually, the older sister abandons being an 'honors student,' and the younger sister begins to be acknowledged by those around her. At that moment, the balance between the sisters starts to break.

- Highlights: 1. The reality of 'sibling comparison' that everyone can relate to. 2. The thrill of the moment the roles of 'perfect sister' and 'incapable sister' are reversed. 3. Delicate emotional expressions by Kaho Yamada and Minon Yajima.
