Let’s start at the very beginning. In 2012, under the label, SM Entertainment, a twelve-member South Korean-Chinese group known as EXO was introduced. The boy band’s name was derived from the term “exoplanet,” which alludes to a planet outside of our solar system.

Moving on to the finer points, the band, which performed music in both Korean and Mandarin, was first split into two sub-groups, Exo-K and Exo-M, in order to appeal to a wider audience. Suho, Baekhyun, Chanyeol, D.O., Kai, and Sehun were members of Exo-K, which concentrated on South Korea, whereas Xiumin, Lay, Chen, and former members Kris, Luhan, and Tao were members of Exo-M, which focused on China.

The sub-groups, however, failed to survive after Kris, Luhan, and Tao left the band in 2014 and 2015 due to legal problems. The members of the Chinese group claimed that the corporation treated them differently than the Korean musicians and that their contract was terminated due to the label’s alleged disregard for their health. The supporters were split on the issue, with one party supporting the departing members and the other seeing it as a disaster.

This significant transition had an impact on the group, even though they continued to release music in many languages as a single unit. Members Chen, Baekhyun, and Xiumin debuted as the Exo-CBX sub-unit in 2016, and members Sehun and Chanyeol debuted as the Exo-SC sub-unit three years later.
