NU'EST W posts creepy prologue teaser for 'WHO, YOU" > K-POP

Get ready, ​L.O.V.E.s​, because ​NU'EST W​ has just shared the first teaser for their impending return!

A few days ago, it was revealed that the four member group would be returning on June 25th. Now, the first teaser has been shared in the form of a 20-second video. With a bit of some creepy music playing, fans can see a window placed in a black background. A girl mysteriously fades into view, staring at the window, but without a reflection, only a shadow.
