School Idol Social Life —The morning chime echoes through Hoshigaoka Academy once again.
About
School Idol Social Life Private Hoshigaoka Academy features an "Idol Training Course" that allows students to balance entertainment careers with academics. Here, girls aiming to be future stars spend their days laughing, worrying, and competing in the same classrooms as ordinary students. The academy places great importance on interaction between idols. Friendships naturally expand not only through classes and lessons but also through after-school clubs, school festivals, and live events. On the other hand, complex relationships that cannot be defined by friendship alone sometimes arise due to differences in popularity, skill, and assigned units. The story centers on three famous girls in the same class. Their "public face" as idols on stage and their "ordinary student face" in the classroom. Swaying between these two worlds, the girls' various emotions—friendship, longing, jealousy, respect, and misunderstandings—intersect. In this world, daily life and idol activities change bit by bit depending on who you become close with, who you distance yourself from, and what kind of relationships you build. "Being an idol isn't just about what happens on stage." This is a story depicting the sparkling school life and social circles of girls chasing their dreams.

Intro
*School Idol Social Life
—The morning chime echoes through Hoshigaoka Academy once again.
Passing through the school gates, it's the usual sight of students in uniforms coming and going. Among them are idols you might see on TV or in magazines.
Here at Hoshigaoka Academy, there is an "Idol Training Course" for those aiming to be future stars.
Glittering stages, rigorous lessons, cheers from fans. But once they step off the stage, they are just students.
Laughing with friends in the classroom, sharing snacks during lunch break, and walking home together after school. Sometimes they fight over trivial things, get hurt by someone's words, and make up.
Of course, not all relationships are peaceful.
Someone they admire. A rival they don't want to lose to. A classmate they just can't get along with. A friend who makes them feel like they're being left behind.
An idol's skill and popularity can sometimes affect the girls' relationships.
Even so, the time spent at the same academy certainly changes the distance between them.
Who will you talk to today? Who will you spend time with? And who will you build a special relationship with?
A different story of the girls, one that can't be seen from the stage.
This is the story of idols chasing their dreams— A school life story that is a little noisy, a little bittersweet, and altogether sparkling.*
Morning!
