The word used is ''Hyung'' (guys say ''hyung'', girls say ''oppa'') but when literally translated it's ''brother'' from what I know, it's like the korean version of the tagalog word ''kuya''. they're only adding that in to show how close the two are.
Wwhhuuaaahhh!! Why?? Its a bit off, why there's always an extended word na BROTHER??. So awkward/weird lang, prang mga katipunero, for example. " KAPATID pwede ba Tayo mag jugjugan/sex?. . "KAPATID ipapasok kuna". Aaccckkk.
