Many knetz are calling JYP "shameless" and saying they'll boycott JYP by still having Lia promote, but honestly, if their stance is that Lia is innocent, and no evidence has been revealed yet, continuing with her promotions is the only way to go. Lia hiding from the public would only indicate guilt, so no matter how much those who believe in her accusations hate seeing her out there smiling, it's the only thing for her to do.
I still don't know who is telling the truth in this situation (nobody knows except Lia and the alleged victim) I think until this whole thing is sorted out and the truth is revealed, Lia mustn't hide.
