In October 2007, SM Entertainment announced that a new Super Junior subgroup would debut in China in 2008. Super Junior's original member Han Geng, and a new member Henry Lau, who performed the violin solo of Super Junior's "Don't Don," were announced to be the first two of seven members representing the subgroup. Some of Super Junior's official fanclub, E.L.F, signed online petitions and held protests to express their dissatisfaction and opposition of adding a fourteenth member to the group, fearing that a new member would mean one of the original lineup would get 'replaced'. Many fans boycotted Super Junior's products and held silent protests in front of SM Entertainment's main building in Seoul, holding signs of the "Only 13" slogan.
Over one thousand fans appeared in front of the SM Entertainment building on E.L.F's third protest on November 3, 2007. Instead of a silent protest, the fans sang various Super Junior songs and shouted "thirteen." Fans purchased 58,206 stocks of SM Entertainment, holding 0.3% of the company's entire stock. They released a statement through the media, stating that they would obtain all chances to prevent SM Entertainment from adding new members and to keep Super Junior as only thirteen. SM Entertainment later announced that they would not add the new subgroup members to the main group.
