Their debut is coming up, but it seems like last minute changes are still being made. Upcoming idol group Co-Ed (????) is now officially a ten member group instead of nine. On August 4th, Core Contents Media stated,

"We were originally planning to have a nine member co-ed group, but because of a grade 3 middle school that has shown us his great talents, we decided to add one more member to the group to make it a total of 10 members. ... This male member fits very well along with the rest of the members. He is young so he isn't really tall yet, but he dances very well and he looks cute." In two weeks, the profiles and photos of the 10 members will be released, and they will debut around the middle of September."
