i think this is translated from korean (i could be wrong) and they might be calling him oppa which translates to brother in english but doesn't technically mean that in korean
in korea the term girls use to call older men is either oppa, which literally translates to brother, or ahjusshi which means uncle.
it does not mean brother like someone related with blood or familial brother or something that sort.
this term is in koreannnn, females call older males usually 'oppa' as an honerific
Ooohhh so it’s in Korea no wonderrrr
I see I seee thank YOUUUuUu~~
Ooooooohhh thank you
Yeah thank YoUUuUu~ Yes they really might be Korea
Brother? But like...isn’t that your lover? Why call them brother that’s a bit...ZzzZ
