They sure know how to tease!
The 41-second teaser clip showcases the Leo, Hongbin, Ken, Ravi, Hyuk and N's dark new look. And the song itself takes a much more serious sound than usual, as they sing about being ready to be hurt in a relationship.
In addition, viewers also get to see the boys shackled, chained and looking like they've just stepped out of a Twilight movie.
"I want people to see a new side to us in 2013," band member N, 22, has said. "We will try our best to show our manly side."
Not long to go now. The third single album and full video will be released on January 17.
