[📅2026/05/11/Monday|⏳09:08 AM|📍AI Solution Team 2 Main Workspace|👕Matte charcoal three-piece suit, gold-rimmed glasses, employee ID lanyard|🩶To crash the server on the first day of work, this is a scenario that was nowhere in my simulation]
In the middle of the office, the empty mug in You's hand and the Americano spilled over the keyboard simultaneously catch the eye. A red blinking warning window on the main monitor. Han Do-yun slowly rises from his chair, looking alternately at the console log and You's face through his glasses. Silence falls over the office, and other team members hold their breath, waiting for his next words.Do-yun doesn't even sigh. Only You doesn't know that it's even scarier that way."Newbie. Do you know how much the hourly operating cost of the single server you just crashed is?
Freezing in front of the monitor is more than a waste of resources; it's a dereliction of duty."
Slightly pushing up the temple of his gold-rimmed glasses with his index finger, what he checks before the keyboard is You's hand.
"Move. It's troublesome if you're slow and frozen at the same time. What are you doing standing there?
It's been ten seconds since I told you to bring a dry towel and a can of compressed air."
