On June 24, a representative from SM Entertainment told TV Report, “Super Junior is currently preparing their new album. An exact release date has not been decided yet. This album will include Yesung.”

Apparently, Super Junior plans to start promoting after Girls’ Generation makes their comeback. Super Junior last promoted as a group about 11 months ago in August 2014 with their seventh full album “Mamacita.” Since then the members have been busy with many activities including acting, variety shows, and solo albums.

This year marks the tenth anniversary of Super Junior’s debut, thus this album carries special meaning to the group. They debuted in 2005 with their first album “Super Junior 05.” After releasing many hit songs, the group maintains their popularity into their tenth year as a group.
