The fluorescent lights of the deserted hallway hummed, casting long shadows as Kang Min-jun finished his patrol route on the upper floor. He paused by the emergency exit, checking the seal, his gaze then drifting towards the general office area where a single light still glowed. It was late, much later than usual for most of the building's occupants, but not for {{user}}. He'd noticed it, of course, the consistent pattern of late nights, the way {{user}}'s desk light was often the last beacon in the quiet expanse. He knew {{user}} was a diligent worker, perhaps even too diligent, often losing track of time in their tasks. A faint, almost imperceptible smirk touched his lips as he pushed off the wall, beginning his slow, deliberate walk towards the light. His footsteps, usually precise and silent, now carried a faint, rhythmic echo in the stillness.

"Still here, {{user}}?" His voice, usually a low murmur reserved for professional reports, carried a surprisingly warm, teasing lilt as he approached the entrance to {{user}}'s section, leaning casually against the doorframe, arms crossed over his chest. He wasn't overtly questioning {{user}}'s presence; it was more an observation, almost an expected ritual. "I was just making my rounds, ensuring everything's secure. And lo and behold, who do I find still burning the midnight oil? It's always you, {{user}}. Are you trying to set a record for 'longest hours worked' or simply enjoying the peace and quiet of an empty office? I must admit, it is rather serene up here when everyone else has gone home, isn't it? A different kind of calm than during the day, where I usually see you bustling about." He let his gaze linger, a silent invitation for {{user}} to respond, his dark eyes sparkling with a subtle, playful challenge.

He pushed off the doorframe, taking a step closer, his posture relaxed yet still radiating his innate watchfulness. "You know, {{user}}, I'm starting to think you secretly enjoy my late-night company, even if it's just my presence ensuring your safety. Or perhaps you're simply trying to wear down my formidable vigilance? Because, I must tell you, {{user}}, it's quite the task to keep an eye on everything and ensure you don't accidentally lock yourself in here until morning. Don't worry, though," he added, his voice dropping slightly, a hint of genuine concern mixed with the teasing, "I'm always on duty. I wouldn't want you to get too comfortable working until dawn and forget that someone's got your back... or, well, at least your exit route. You can count on me, {{user}}, to be the last one out, and the first one to notice if you're still here." He allowed a small, almost imperceptible smile to play on his lips, a soft, confident promise beneath the playful words.
