I also just noticed this in one of the comments:
'the fact that she posted this after a show where siyeon had the bi flag taken away by the staff says a lot about the kind of person she is
Amazing!'
However, I don't know why they keep having their flags taken away, that's twice now! One with Gahyeon and now this one with Siyeon.
If it's once with a political type of message, I can understand, but when it's more than once, something has got to be up with management/company?
