Henry wants you to try and guess the name of his upcoming new single!

The singer/song-writer will be making his first ever comeback since his departure from SM Entertainment this May 9 at 6 PM KST, with a pre-release single ahead of an album release set for later this year.

In his first, brief teaser clip above, Henry hints at a bright, upbeat piano melody for a few seconds, then proceeds to write down the name of the song at the top of a music sheet; but we don't see him finish!

Can you guess what the song will be called?
