Many idol trainees that are labelmates often train together with no clear idea about which group and what position they’ll be holding once their training period is over. The only goal they have is debuting, whether it be as the maknae in one group or the leader in another. Therefore, many times, the original line-ups of a group look drastically different from the final one that debuts. Trainees are shuffled and assigned to groups that suit them, and therefore, your favorite idols may very well have been in another group had their company so decided.
Miyeon was part of the original line-up of BLACKPINK. BLACKPINK was supposed to be a 9 member group, but YG Entertainment decided at the last minute that it would be a 4 member group instead. Therefore, despite being so close to debut after 5 years of training at YG, Miyeon was removed from the line-up. Miyeon went on to leave YG Entertainment and joined Cube Entertainment, where she was able to debut in (G)I-DLE. However, there are no hard feelings between the girls themselves as when Miyeon finally debuted, all 4 members of BLACKPINK congratulated her for her success.
Shownu was almost a part of GOT7 before he left the company due to training absences and joined Starship Entertainment. He worked as a dancer for Lee Hyori before appearing on No Mercy and ultimately joining MONSTA X. Shownu is still incredibly close with the members of GOT7, especially Jinyoung and JB, and Shownu even looked up to them for advice while he was on No Mercy.
BamBam was not in the original line-up of GOT7 and was supposed to debut in a different group slated to debut after GOT7. However, on the show 'WIN: Who Is Next?', the CEO of YG Entertainment was highly impressed by BamBam's talent for dancing and performance. It was probably then that Park Jin Young decided that he should be in GOT7 and added to the line-up soon after.
S.Coups came close to debut quite a number of times before she could actually debut. He was supposed to be a part of NU’EST but was removed from the final line-up.

Hansol was almost definitely going to be a part of NCT but decided to leave SM Entertainment after training for 6 years before that could happen.

He joined J-Flo Entertainment and debuted as a member of NewKidd soon after.
Timoteo was supposed to be a member of EXO and even earlier, he was also chalked up to be a member of SHINee. However, he could not pass evaluations and ultimately could not debut in either group.

Soyou does not seem to have any qualms about her removal, however, as SISTAR had quite a great run too.
