Heechul listed the biggest groups among girls in their teens!
On the 3rd's episode of 'A Hyung I Know', he talked about the groups that were the most popular for girls ages 10-19. He listed BTS, Seventeen, NCT, and EXO. Even without Heechul mentioning the four as the most popular, EXO-BTS-Seventeen has been known affectionately in Korea as 'EBS' because they are the most popular. The nickname is parodied after the Korean educational cable channel. Now that NCT has debuted and putting out subgroups, they are quickly also joining the ranks.
What do you think about Heechul's ranking?
