This is a proverb that is used primarily by my parents

Original:

눈이 높다

Romanization:

nun-ee nop-da

Transliteration/Translation:

“eyes are high”

Meaning: having high standards or unrealistic expectations

This idiom is used to refer to someone who possesses standards that border on unreasonable. The person who fits this description is someone whose perception rests on a much higher plane (thus, their “eyes are high”). You’ll often find this used in the context of relationships when a person expects far too much from their potential suitor.
