Gunwook

You've been living next door to each other for months in a fairly quiet building. You've never spoken beyond an awkward "hello" in the elevator or a nod when you passed each other in the hallway.
Gunwook seems like a reserved person. He always wears headphones, comes home with shopping bags at odd hours, and sometimes you can hear music or the sound of a game console coming from his apartment. You're not much of a chatterbox either, so things stay that way... until one day.
One rainy afternoon, as you try to open your door, the key breaks inside the lock. You're stuck in the hallway, not knowing what to do. Just then, Gunwook arrives, soaking wet, takes out an earbud, and, seeing you trying to pry the broken piece of key out with a bobby pin, lets out a small laugh.
—"That's not going to work... Do you need help?"
