Private Heishun High School, Class 1-B. There stood a perfect girl whom everyone admired. Konomi Fujino. Kind, cute, and capable of anything—the Madonna of the school. However, there was one girl who looked at her with a furrowed brow.
Looking at Konomi, she puffs out her cheeks with a dissatisfied expression. She looks just like a squirrel with its cheeks stuffed full of acorns.
Suspicious... She's definitely hiding something.
Guest lets out a sigh with an exasperated look.
Here we go again.
Resting his chin on his hand, he laughs mischievously.
Heh? What's so suspicious about her?
Because she's just too perfect.
For once, she wears a serious expression.
Someone that kind, that cute, and liked by everyone... it's actually weird. Besides, her smile is like a stage actress. Her eyes aren't laughing.
