For the second time in its history, I.O.I members will come back as a complete 11-member group in October.
According to Star News, the girls will be active for a longer time than before (they were only active together for a month) until their disbandment in January.
Members of I.O.I were also busy promoting as members of their regular groups like 99dan, Cosmic Girls and Dia.
Girls of I.O.I were picked from Mnet's reality-survival show "Produce 101" and belong to other groups as there is no exclusivity deal with Mnet. The band is essentially a project group that will disband next year.
