"Begin" is the sixth single that TVXQ released in Japan back in 2006 when the five boys were actively promoting as Tohoshinki. In the clip above, you can hear some fans weeping in sorrow overwhelmed by their nostalgic feelings.
International netizens were pleasantly surprised that JYJ had performed the song even with the separation and the changes that came along with the disbandment.
One netizen wrote, "Though I'm certain a reunion will never happen, I'm always happy to see JYJ giving back to the fans with the acknowledgment of, yes, they were in TVXQ."
