Remember how super junior was 13 and will always be 13. But that changed pretty soon. It was unexpected. Kangin, Kibum, and Hangeng, apart from the rest of Super Junior and their activites. Now in the present, Heechul as well, and Siwon busy with Posiedon, only 8 together for now. It seems to be that 1 by one, they would go and come back if they could, while others tend to stay in the shadows of what they used to be. This is the leader's sweet memoris of the past.
