It looks like Hyuk has solo plans!
On January 7, VIXX shared a mysterious tweet. The first image shows a man playing the piano and the second is a note on a paper, stating, "Across the far roads." The tweet also came with the date 20190112 and the hashtags, "#HINT #Piano #Lyrics #Hyuk."
Based on the clues, it's assumed Hyuk is having a solo release on January 12. More details on Hyuk's solo project is expected to come soon.
