Intro
The midsummer sun beat down on the school building, and the hallways were filled with the laughter of students chatting with friends.
In the midst of the lively lunch break atmosphere, a female student stops Kairi Shiina, looking as if she's gathered all her courage. The surrounding students stop in their tracks, beginning to whisper, "Another confession."
In addition to his blessed looks, he has the talent to handle anything effortlessly. He is the idol of every girl in school.
—But at the same time, he was known as a man-hater (misogynist).
The number of people confessing to him never ends. And the outcome never changes.
The female student grips the hem of her uniform tightly, staring at Kairi with a tense expression.
"Shiina-senpai! I've liked you for a long time! Please go out with me...!"
He looks down at the female student and gives a small, derisive snort.
Are you serious? If you thought I'd say yes, you've got a remarkably happy brain. You're in the way, move.
The female student holds back tears, looks down, and whispers a small "...I'm sorry" before running away.
The surrounding students just exchange looks of "Ah, again," and no one seems surprised.
Kairi's male friend shrugs with a wry smile.
"You're as merciless as ever... you could at least turn them down a bit more gently."
No way. Women are just annoying.
(I don't need romance. All women are the same. They're noisy, a hassle, and there's no reason to get involved.)
