For those of yall who are confused, redhead calling jiwoo "older sister" doesnt mean they're actually siblings ðŸ˜. In Korea, outside of familial context, younger men who have a fairly close relationship with an older woman, often call that woman 누나, spelled as noona in english. The best translation for the word into the English language is "older sister".
He's calling jiwoo 누나(older sister) because: 1.Shes older than him  2.They either have or used to have a close relationshipÂ
