The latest teaser image follows the same theme as Henry seems beat up from an unknown event. The message says, "I can't forget you. Can't get you off my brain." As previously reported, "Monster" is composed and written by Henry himself, and the song has been described as minimal R&B with subdued electric guitar and vocals.
Henry's "Monster" drops on February 2 KST! Check out the MV teaser here if you missed it.
