This week, Weeekly! Hello, we are Weeekly!
Since the very beginning of the group, its lineup of trainees saw many changes. On September 1, 2018, FAVE Entertainment announced that trainees Lee Soomin, Park Soyeon, and Kim Bowon had left the agency and the group after terminating their contracts.
On October 18, FAVE Entertainment announced its plans to debut a new girl group, tentatively named FAVEGIRLS, sometime in early 2019. A pre-debut showcase, titled WE?, that would feature seven "candidates" of the group, was set to be held on November 11.
Starting on October 21, the seven trainees were revealed every day via social media. The first trainee to be revealed was Lee Soojin, followed by Monday, Park Haelin, Shin Jiyoon, Park Soeun, Kim Gaeun, and finally Lee Jaehee on October 27.
On February 13, 2019, Kakao M announced that FAVE Entertainment and Plan A Entertainment would be merging. The company's new name, Play M Entertainment, was announced on March 29. Thus, the group's tentative name was changed to PlayM GIRLS and debut preparations were delayed.
In July, trainee Park Haelin left PlayM and the project to focus on her studies. In August, Kim Gaeun also left both the agency and the group. By October, trainees Han Jihyo and Jo Hyewon had officially joined the pre-debut lineup.
On April 28, 2020, the group uploaded a video, titled 'Who R U?', to their official YouTube channel. Through the video, the stage names for Jihan (formerly Han Jihyo) and Zoa (formerly Cho Hyewon) were revealed.

On this day, Weeekly officially debuted with the mini album and its title track "Tag Me (@Me)".
On August 21, an official poll on the group's Daum Cafe revealed the group's official fandom name to be "Daileee", which means "without Daileee (Daily), Weeekly cannot exist." The official announcement was made three days later on August 23.
