IT IS TIME FOR MURDER!
As in, it is time to be murdered in cold blood by UP10TION, every single one of them.
JUST LOOK AT THEM.
They teased the actual teaser video with a teaser image in black and white. The one that involved showing skin (thanks Xiao and Wooshin, I didn't need to breathe anyways!) and promised a concept that would be manlier!
"This comeback image brings out a message that, prior to UP10TION’s comeback, they are preparing a new image. The black and white photo of UP10TION gives a more manly aura. On the top of the photograph it’s written ‘20160418 00AM’ - the comeback date announcement."
