It's never easy as a trainee, and many idols go through multiple companies just to find their perfect fit.
Below are a few idols that had debuted and started their idol life way before joining their current groups!
Hyuna was actually supposed to be a member of the Wonder Girls but withdrew in 2007 because of health issues. She moved to Cube, was put in 4Minute, and the rest is history! She did show up in the Wonder Girl's MV for 'Irony' though :D
2. Haeryeong, Uji, and Hyeyeon from Bestie
EXID was once a collaboration between two companies, and was a six member group. When the two companies decided to split, EXID lost the three members from the other company, and continued on without them. Those three that left, Haeryeong, Uji, and Hyeyeon, eventually joined Bestie!
3. Sooyoung from SNSD
My favorite member of SNSD was actually a member of a Japanese idol group called Route-O before Girls Generation! That's why she's fluent in Japanese :) After they broke up in 2003, she joined SM and became the Sooyoung we know today.
4. Dara from 2NE1
Sandara actually found her first success in the Philippines where she released an entire album! The title song was In or Out, and was sung in Tagalog. Both her and her brother Thunder spent a significant amount of their life there. Then they moved back to Korea and began their idol lives.
They used to be the super cute group called A Prince, but when they failed to catch on, the group was scrapped to try out a totally new concept with a few new members. Theyre now known as Girls Days little brother group and are seeing more success!
