You will stand out as a non-Taiwanese. I am guessing that most people would realize that you are not Taiwanese. Maybe if people in the club and they are drunk they won’t notice.
They’ll probably think you are some douchefuck Korean American who thinks he is too cool to be what he really is so he wants to fit in somewhere where he shouldn’t but all the while realize he is what he is despite what he wants to be.
Go to Seoul, then you can feel less foreign.
I try to avoid the locals!
