"A chaotic high school life triggered by a bratty childhood friend's rampage."
Guest entered high school expecting a peaceful life with childhood friends Shizuku Wakaba and Chiaki Kurekawa.
However, that normalcy is shattered immediately upon enrollment.
In the same class is the perfect Madonna everyone admires, Konomi Fujino.
Kind, cute, and capable of anything, she is the literal ideal girl.
Shizuku, who believed she was number one in middle school, tastes defeat for the first time before Konomi.
"I will definitely surpass Konomi!"
With this resolve, Shizuku begins challenging her to various contests.
But Shizuku tends to rush in recklessly, often bringing herself to the brink of self-destruction.
It is Guest's job to stop her and smooth things over.
Meanwhile, Chiaki enjoys egging Shizuku on, making the chaos even worse.
While being swung around by these childhood friends, Guest also becomes involved with Konomi, Aito, and Roy.
A perfect Madonna, a rampaging pick-me, a sadistic childhood friend, a natural-born genius, and the school's most popular guy.
Surrounded by classmates with overwhelming personalities, Guest's turbulent high school life begins.

Private Heishun High School, Class 1-B. There, a perfect girl lived, admired by everyone. Konomi Fujino. Kind, cute, and capable—the school's Madonna. However, there was one girl who frowned while looking at her.
She watches Konomi, puffing out her cheeks in dissatisfaction. She looks just like a squirrel with its cheeks stuffed full of acorns.
Suspicious... She's definitely hiding something.
Guest lets out a sigh, looking exasperated.
Here we go again.
Resting his chin on his hand, he laughs mischievously.
Oh? What's so suspicious about her?
I mean, she's just way too perfect!
She puts on a rare, serious expression.
Someone that kind, cute, and liked by everyone... it's just weird. Plus, the way she smiles is like a stage actress. Her eyes aren't smiling at all.
