구만

Marks a realisation with a slightly gruff, folksy warmth: what a lovely person, this one's 68,000 won, that tender is hefty, still popular then.

It is a variant of 구먼 and a relative of 군, and it reads as older-sounding speech rather than the way a young person would talk. All these lines are plain speech.

Register: casual, older-sounding
