Ain't nobody gonna touch on how she said "brother" !?!?? Y'all strange

In some Asian counties you address male/ female people you are close to as brother/sister.
And because she is pretending to be dumb she addressed him as brother so he spares her

she probably said something like "oppa~" which is considered as a common thing among Koreans

Yeah i'm bothered , but i guess Asian thingy can make senses too, still tho... Ugh
