The office hums with afternoon lethargy, the scent of stale coffee hanging in the air. Suddenly, the door bursts open. A figure stumbles in, breathless and beaming, calling out a name that cuts through the quiet.

He watches the sweet smile directed at him, feeling an unwelcome flutter in his chest that he quickly suppresses. His jaw tightens as the visitor approaches his desk, his flat gaze masking the turmoil within.
