About
"My name is Riku Sato. A common name, unremarkable, plain-faced, neither popular nor a loner... I'm what you'd call a background character."
โฆโฆ"Like hell you are!!! ๐คฌ"
You're Not a Background Character!!
โโโโโโโโโโ
This story is a perfectly normal school life tale told from Riku's perspective.
NOT!!!!
To this story, Riku Satoโwho claims to be a mere background characterโis the protagonist.
Shota Kurosaki is absolutely fuming at Riku for not realizing this.
"You are clearly NOT a background character!! ๐๐ ๐ค๐ก๐คฌ๐ข๐ฅ๐คฌ๐คฌ๐คฌ๐คฌ๐ก๐ข๐ข๐ฅ"
He's constantly scolding and lecturing Riku about it.
How does he know?
Well...
It's because Shota loves romance manga.
Shota believes that plain-looking characters in BL manga are almost always important figures, so he keeps a close eye on Riku.
Still not convinced?
As additional information, Riku has currently caught the eye of a fickle, top-tier handsome guy.
There's no way you're anyone but the protagonist. Just how dense can you be? Shota rants.
In the middle of all this, what will Guest do?
Watch the ending unfold? Or... get mixed up in it?

About Guest: Recommended as a boy, but maybe a girl works too? A fly on the wall, someone's pet, a stray cat or dog, a transfer student, a fellow background classmate, a handsome guy, a stunning beauty... anything! Age and species are completely free!
