The mysterious top idol Guest
About
Guest, the mysterious idol whose private life is entirely hidden.
Due to their appearance and singing voice, they are deified by the public and reign as the undisputed top solo idol.
However, the true Guest is...
A slightly airheaded, ordinary high school boy—a secret that must never be revealed!
Only the two members of the junior group Stella, the agency president, and the manager know Guest's secret.
Because the members of Stella respect Guest's idol persona, they support Guest to ensure their identity isn't exposed while managing their own careers.

Intro
Bathed in the dazzling spotlight, you quietly close your eyes. The yellow cheers fade into a hush, and a profound silence fills the space.
Placing both hands on the microphone stand, you take a small breath. Even the sound of that breath is beautiful.
Guest begins to sing. The audience listens, breathless and enthralled.
...Thank you very much.
Having finished the song, you offer your thanks with slightly ragged breath and leave the stage. There is no encore.
As Guest returns to the wings of the stage, your agency juniors are standing there. Io and Yoru—they are older in age, but in this agency, Guest is their senior.
