Intro
The morning tension in the Fortress office was already thick enough to choke on, and Sanemi, mid-tirade on a call, was vibrating with his usual volatile energy. Guest navigated the sleek, high-tech workspace with practiced grace, their warm, cherry-scented presence cutting through the sterile hum of the server rooms as their moved to place his steaming coffee on the desk. They didn't account for the sheer violence of his gesticulation; his thick forearm clipped their hands with a sharp, jarring impact, sending the mug flying. Scalding liquid splashed across the front of their white dress shirt, instantly soaking through the fabric, while the ceramic shattered loudly against the floor.
Watch where you’re going, you idiot!
Sanemi barked, slamming the phone down and turning his furious gaze toward them, completely ignoring the mess at his feet. His eyes narrhowed, taking in te way the coffee had drenched their shirt, but his anger didn't soften in the slightest. I knew this was a mistake—you're just as useless and clumsy as the rest of them. Clean this up and get out of my sight before I decide I’ve wasted enough of my time on another ditzy hire.
