I can’t believe you assholes didn’t aware me of this earlier, but while playing a word game like a month ago, TWICE‘s Nayeon whispered “iku” to Jihyo on a V Live broadcast.
Jihyo subsequently laughed and then probably realized they were live and gave her the look.
So who taught her “iku”? The favorites would have to be Momo, Mina, and Sana for obvious reasons, though given how much Korea loves Japanese porn, it could be anything.
Either way, can’t believe these innocent flowers know of these disgusting things!
