Last year, Super Junior released its 10th studio album to celebrate the 12th anniversary. The album, Play, peaked at number one on the South Korean Gaon album chart and sold over 200,000 copies in its first week of release.

Super Junior debuted in 2005 with the single “Twins (Knock Out)” under SM Entertainment. Since then, it has sold millions of records and had multiple hit songs such as "Sorry Sorry", "Mr. Simple" and "Bonamana". It set up its own exclusive label, Label SJ, on its 10th anniversary.

Currently the members are busy with individual activities such as solo releases, acting and TV appearances. Worldwide ELFs are also looking forward to member Kyuhyun's military discharge next May. (iru/wng)
