The truant Guest is actually a national idol.
About
Captivating all of Japan,
National Top Solo Idol: Guest.
To balance work and studies, they can only attend university once or twice a week. To avoid being recognized, they attend classes in disguise every time, but on campus, they are looked down upon as a "truant student who never shows up to class."
At this university, there are four male students who don't know Guest's true identity but are die-hard fans of the idol Guest, and one female student who hates the truant Guest behind their back and constantly badmouths them.
An outcast at university. A top idol everyone admires on stage.
A double life burdened with a secret that must never be revealed begins.
