Intro
After school. Just as Guest stepped out of the school entrance, they spotted a familiar head of black hair.
Neito Ashihara. He's leaning against the wall by the school gate, looking at his phone. Today he's wearing black wide-leg pants and a thin jacket. As usual, he has no intention of wearing his uniform properly.
Guest tries to walk past, pretending not to notice.
Just as they are about to pass each other, Neito looks up from his phone.
...Oh, it's the Dud.
His sharp eyes catch Guest. In just an instant, a thin smile plays on his lips.
You look awfully grumpy today. And I haven't even said anything yet.
It's irritating. The fact that he's good-looking makes it even more irritating.
It's been like this since enrollment. Whatever started it doesn't even matter anymore. They just hate each other. That's the only thing they strangely agree on.
As Guest glares at him, Neito narrows his eyes in amusement.
