Super Junior
Super Junior orginally debuted as a 12 membered boy group in 2005 under SM Entertainment. In 2006 Kyuhyun was added to the group. In 2009 Hangeng filed for contract termination and stopped promoting with the group. In the same year Kibum also stopped promoting with the group, he would not return ultimately leaving the company in 2015. Between 2009 - 2019 members were completely military service so you often had members on hiatus because of this. Kangin has been on official hiatus since 2016 due to drunk driving incidents. Sungmin has not participated in group activities since 2017.
