NU'EST member Ren has been one of the most talked about K-Pop idols throughout various online communities in South Korea at the moment.
The idol group uploaded a dance practice video on July 27th, dressed up in various different costumes.
As you'll see in the video clip, Ren's costume was the one that shocked netizens the most as he was barely recognizable from his usual self.
He played the role of "cavity".
However, some netizens and even fellow members found his attire a bit scary. The members also jokingly asked him not to look at them as well.
