Eight. Eight who would change the world. With there name, They will be the Best Rookie of the year. Application on First Chapter. . They started with 8 members but since maknae Ji Ae had scandals and proclaimed them true, Ji Ae herself resigned and graduated. For about 3 months they experimented the effect of having 7 members and without Ji Ae. Suprisingly, the sales increased only a bit, but they did not expect the sales would increase. So, SM planned to add 4 members, with extraordinary talent and impact, the sales increased a lot. Now they currently have 11 members
