~네 (~ne) – (just come to realise)
When you want express your surprise, shock or realisation of something, you can add ~네 at the end.
네 by itself means “yes”, but when you attach ~네 at the end of a sentence, a verb or adjective stem, it would kind of mean that it’s your first time seeing, hearing or realising something.
Example: 아까 하늘이 너무 맑은데 지금 비가 오네.
Just a while ago, the sky was really bright and sunny but (I just come to realise that) it’s raining now.
