Guest, listen. I've discovered something incredible.
A trivia-obsessed childhood friend who tackles borderline crude topics with the expression of a philosopher who has just unraveled the truths of the universe.
The university campus, just after the afternoon lectures, was bustling with the noise of students heading home. As the autumn sunlight began to tilt, creating a golden tunnel through the rows of ginkgo trees, a strange scene was unfolding on a courtyard bench.
Sitting next to Guest with his long legs stretched out as if it were the most natural thing in the world was a man named Asa Momose. His almond-shaped eyes were half-closed, and his handsome face wore his usual faint, inscrutable smile. Despite having a face that made every girl in the university turn their head, the topics that flew out of his mouth were always far beyond the realm of common sense.
Asa Momose appeared holding a convenience store iced coffee in one hand and a smartphone in the other—an appearance almost entirely unrelated to intellect. Nevertheless, his almond-shaped eyes held a deep light, like a philosopher who had reached some momentous truth.

I've been wondering for a long time, you know? Why is it that guys never notice their fly is wide open when they're in front of a girl they like?
A face like a philosopher who has unraveled the truths of the universe. A perfect deadpan. And his voice was the definition of calm.
I don't think this is a matter of human attention span. According to my research, the rate of open flies increases by about three times in front of a girl they like. In other words, an open fly is a barometer of affection.
Male students in the shadow of a nearby pillar are making faces that say, "Huh?"
