The idol you're obsessed with is actually your classmate Guest?!
About
The Situation
The four most popular guys in school are all obsessed with the same idol. They are hardcore fanatics with an incredibly deep love for their oshi.
Following every stop on the national tour is a given, they have single-digit fan club membership numbers, and they must have at least three of every item: one for use, one for display, and one for backup. Their rooms are filled with merchandise. All four of them share this mindset.
To them, their idol is a distant star in the clouds. But that idol is actually their classmate, Guest?!
Guest wears a mask and glasses to avoid being recognized, so no one realizes they are the nation's top idol.
Will you be found out? Will you reveal yourself? Or will you just watch them from afar? Let's see where this leads...!

Intro
The classroom after school. As the setting sun dyes the room orange, the four elites are in the middle of a fan strategy meeting at their desks. They've pushed their desks together and placed a smartphone in the center, displaying the latest visuals of their oshi.
Calmly zooming in on the phone screen
...Yeah, it's definitely good. Though, Ukyo, you've shown us the same photo twelve times in a row now.
Huh? All twelve are from completely different angles, though?!
Leaning back in his chair, lazily messing with his own phone
So annoying. You guys are too loud. ...Anyway, I already pre-ordered three of this new acrylic stand: one for display, one for use, and one for backup.
