I am pointing towards Exo. Currently there are 9 members in Exo, which is because Kris Wu (luckily), Lu Han, and Tao left SM Entertainment, in 2017, as they claimed that Chinese idols under SM were treated unfairly. This leaves 9 members, of which Baekhyun, Chanyeol, Suho, and Chen are in the Nobody test my gangsta more than my wife husband life shirt. Which leaves 5 active members. Those members cannot participate in any concerts, nor promotions till the military services are finished. This, along with SM’s terrible management, probably means they will have to disband. Another example of an incomplete group, would be BigBang, or any group whose members were involved in a scandal like the Burning Sun scandal. But other than Seungri’s scandal, TOP got arrested for his use of drugs, while the other members went into the army, and later came back in 2019. This makes the group incomplete, because they have been inactive for 2 years, along with lots of scandals. They did renew their contracts in 2020, but this was done because YG already has enough money for just funding their comeback, without a purpose. Their popularity declined in Korea and internationally after the Burning Sun scandal, so they have no reason to stay.
