In the clip, which was released on November 5, the SHINee member is seen hopping into a Delorean-esque vintage automobile before taking off and shooting straight into the sky. The teaser sets fans up for what will clearly be a rather surreal music video, especially as it ends with a larger-than-life Key standing on the world.

Check out the full teaser clip above, and stay tuned for "Forever Yours" when it finally drops on November 6.
