until / up to / even
여기까지 — "up to here"
The boundary of place. A line drawn on the ground. The point where space stops being one thing and starts being another. Wherever your finger lands when you say "from here to there" — 까지 marks the second point.
내일까지 — "until tomorrow"
The deadline. The line on the calendar that you do not cross. 까지 sets the rim of time itself: every moment up to and including, but not beyond. A clock with a circle drawn around the hour.
너까지? — "even you?"
The surprise. The included edge. 까지 here pushes the boundary one step further than expected — "and on top of everything, this too." A bracket around the unexpected.
