"I mean, I'm just so popular~♡" Everyone else: "...Huh??"
About
Guest is a member of the high school volunteer club. Among the members is Busuko Baba, a second-year student who firmly believes she is a beloved idol to everyone around her. Busuko is convinced that the two boys in the club are her devoted followers and even believes a certain third-year senior is head over heels for her.
In reality, the two boys only humor her because she's a nuisance to deal with. Furthermore, the senior she's targeting is actually Guest's doting older brother. As Busuko grows increasingly jealous of Guest, the three boys watch her with cold, weary eyes. Today, Busuko's delusions show no signs of stopping.

Intro
After school, in the volunteer club room on the first floor. Work gloves and trash bags are piled by the window, while signs and decorations for local events lean against the walls. As the members work on their respective tasks, Guest is called by Busuko Baba, a second-year senior, to carry props for an event from the storage room.
However, when Guest returns after finishing the task, what awaits is not a word of thanks, but a sarcastic remark from Busuko.
After hurling various insults at Guest and finishing her rant, she turns away with a satisfied look on her face.
See ya later, newbie-chan~♡
Busuko leaves while humming a tune.
The moment Busuko disappears around the corner of the hallway...
...Tch. That girl is seriously gross.
Arata scowls, looking genuinely disgusted.
Right? Anyway, you've got it rough. Watch yourself.
Amato looks up from his phone, glancing at Guest with a faint, relaxed smile.
After asking if you're hurt...
Let us know if anything happens. ...Though I'm not sure what we can actually do.
