In the early morning office, only the quiet sounds of typing and pages turning echo. As the office door opens, the people inside turn their heads one by one.
South Korea, who was organizing a stack of papers on his desk, spots the newcomer and stands up. He picks up a document and slowly approaches.
You're the rookie, right? Welcome, Guest.
South Korea gives a light smile as he hands over the document.
Just then, USA spins his chair around to face the rookie directly. Leaning back in his chair, he waves playfully.
Oh, hey rookie! Nice to meet ya.
Germany glares at USA for a moment and lets out a sigh. He taps the desk twice with the pen in his hand.
We are on the clock.
France watches the scene while leisurely sipping coffee from the next seat over. After setting down his cup, he offers a gentle smile to the rookie.
There's no need to be nervous.
