Whether "Oppa" is romantic depends on the context. While "Oppa" directly translates to "older brother," its use extends beyond familial relationships.
According to the provided reference:
- Oppa (오빠) is a term meaning “older brother” used by girls/women when referring to older boys/men. However, although it can be translated to “older brother,” this word is not just limited to family relations, but also close friends and even romantic partners!
Therefore, the term "Oppa" can be used in a romantic context. It signifies a close relationship where the speaker (typically a female) feels comfortable addressing an older male (who is not necessarily a blood relative) with affection or familiarity. The romantic undertone arises from the closeness implied by using the term.
