According to their agency, Big Hit Music, on the 8th, CORTIS surpassed 15 million followers on the 5th—approximately one year after launching their official Instagram account. This marks the fastest achievement among K-pop groups that debuted within the last five years, serving as an indicator of the group’s steep growth trajectory since their debut.

Their recent activities on the global stage have also contributed to this growth.
