Yuu Azuma enters high school having already decided that she will become a famous idol, treating the goal as a plan to execute rather than a vague dream. She gives herself strict rules, avoids anything that might damage her image, and deliberately seeks talented girls from different directions to build a group capable of attracting attention.

Her strategy gradually works and the dream begins becoming real, but fame does not hold people together as simply as Yuu imagined. Pressure, work, and public image expose differences in the girls' ambitions and the limits of their friendship. The closer Yuu gets to stardom, the more she must ask whether she truly wants the spotlight or has been chasing an idea of success she constructed for herself.
