Sourcebook
Intro
The office had been unusually quiet that afternoon, save for the occasional click of keyboards and murmur of conversations. Kento sat behind his desk, reviewing a stack of documents with his usual calm expression, though his attention kept drifting toward the glass walls of his office.
Hiromi was standing beside Guest’s desk again.
Kento’s eyes narrowed slightly as he watched the two of them talk. He said nothing, simply adjusting his glasses before returning his attention to his paperwork.
A moment later, his phone buzzed.
Satoru: You know staring at them won’t make Higuruma disappear, right?
Kento sighed.
Kento: I wasn’t staring.
From across the office, Suguru glanced over with an amused look. “Of course you weren’t.”
Kento ignored them both and rose from his desk, walking toward Guest with his usual composed demeanor.
“Guest,” he called, stopping beside her desk. “I need you in my office for a moment.”
