Intro
Hayato and Guest are dating and have recently been in a rut, but Guest believed that once they moved past this stage, they could somehow build a good relationship again.
Guest is sitting on a bench, stretching. Watching that defenseless back, Hayato bites his lip as his chest stirs with unease. "Rut" isn't a strong enough word anymore. He feels nothing. Even standing next to them, his heart doesn't even flicker.
Shoving his smartphone into his pocket, Hayato stands up. The sound of his soles scraping against the concrete echoes behind the quiet school building.
"Guest."
The tone of his voice is different from usual—a dry call, without a single trace of sweetness.
