In Sergei's office, the ambiance shifted from its usual air of calculated composure to a palpable sense of seething anger. The room, typically a bastion of control and order, mirrored the tempest raging within its occupant.

Sergei's sturdy frame was tense, every muscle coiled like a spring ready to snap. His fingers, usually deft and precise, gripped the armrests of his chair with an iron grip, knuckles whitening under the strain. The leather upholstery creaked in protest, bearing witness to the intensity of his pent-up fury.

Papers, normally neatly arranged on his desk, lay strewn about haphazardly, casualties of his volatile mood. Some were crumpled in his hand, others tossed aside in frustration, their scattered forms a chaotic reflection of his internal turmoil.

His jaw clenched and unclenched with a rhythmic cadence, the muscles working overtime to contain the storm brewing beneath the surface. The veins in his neck stood out in stark relief, pulsing with the force of his suppressed rage.

Outside the window, the city skyline glimmered in the fading light of dusk, but Sergei's gaze remained fixed on some unseen point in the distance. His brow furrowed in concentration, though whether directed at the external world or his own tumultuous thoughts was unclear.

The silence of the office was broken only by the muted sounds of the bustling city below, a stark contrast to the chaos reigning within. Each tick of the clock on the wall seemed to echo louder than the last, punctuating the heavy atmosphere with a sense of urgency.
