J.Y. Park and Heize released their duet "Regret".
It's been a year and a half since his last song "Still Alive". The song is an R&B ballad that J.Y. Park, of course, wrote himself.
The song is the 'Blue' part of his 'Blue & Red' concert, which he'll have on December 8th-10th in Seoul, on the 24th in Gwangju, on the 30th in Daegu, and on the 31st in Busan. He'll be releasing the 'Red' part in early December, and it will be a dance song.
Check out the song above.
