Pre-debut
Before joining JPlanet Entertainment, 3 out of 4 members were previously involved in the music industry. Previously, Taeryeong was a contestant on Produce 101 but she was eliminated and ranked at 57th place. She also was a participant in Mix Nine but she was eliminated and placed at 46th place. She was seen performing with girl group A-Daily in October 2018, but she was never announced as an official member of the group. She was also part of ONO Entertainment's pre-debut girl group Blackmamba.

Jian was a former member of girl group S.E.T with the stage name TaeE and participated in The Unit: Idol Rebooting Project but was eliminated and placed at 61st place.

In 2018, JPlanet Entertainment announced Rookie Planet, a project to promote their trainees (or "rookies") to the world before their official debut. They often posted dance covers, vocal covers, and reaction videos. The members were revealed within a 1 year period, starting with Jieun (who later became Jian), Taeryeong, Hyeonjeong (who later became Eseo), Yuuri, and Sujin. Sujin left sometime in early 2020. On March 27, 2020, Jian appeared on I Can See Your Voice 7, as well as being a cover muse for the YouTube channel MUPLY.
