According to Koreaboo, recently, some unreleased videos of Blackpink members have been leaked on YouTube, by a person claiming to be a former employee of YG Entertainment.
In the series of videos, the trainees competing to debut in the Blackpink lineup performed songs by other artists and performed choreography in groups.
In addition to Jisoo, Jennie, Lisa and Rose - 4 artists who have officially debuted in the final lineup of Blackpink, netizens pay special attention to Miyeon (currently a member of the group (G)I-DLE) - who was in the 5-member lineup of Blackpink before the group officially performed with 4 people.
In particular, the audience's reactions to Jisoo and Miyeon are contrasted.
Although Jisoo was eventually selected for the official lineup, Nicki Minaj's cover of "Right By My Side" performed by Jisoo as a trainee caused controversy.
Many people thought that Jisoo's voice was not enough for her to debut as an idol. Jisoo is said to sing much less well than Jennie, Rose and Lisa.
In contrast, Miyeon is praised for her potential with a stable voice while still showing her smooth dancing skills with the group.
Many articles expressed regret that Miyeon finally did not debut in the group Blackpink. However, many audiences were also happy when Miyeon joined (G)I-DLE, where her unique appeal shone the most.

The story of Miyeon being a "missing member" of Blackpink has long been known to Kpop fans. Miyeon has been a trainee at YG for more than 5 years and has become a strong candidate in Blackpink's official debut lineup.
But she left YG in February 2016, just 6 months before Blackpink officially went live, with the debut songs "Boombayah" and "Whistle". After that, Miyeon signed a contract with CUBE Entertainment, debuting in the group (G)I-DLE in 2018.
The exact reason why Miyeon did not debut in the Blackpink lineup has not been revealed, but there are many speculations surrounding this issue.
It was reported that Miyeon was left out of the squad for dating a contestant on the survival show "Mix and Match", while YG stipulated that trainees are not allowed to date.
Another speculation is that the reason Miyeon left Blackpink was because of the overlap in her image with Jisoo.
Despite leaving YG, Miyeon still maintains her friendship with Blackpink. She shared on a radio show that she received a congratulatory message from the Blackpink members when she debuted with (G)I-DLE.
Miyeon and the members of the group (G)I-DLE also came to cheer for Blackpink's concert many times and vice versa.
In particular, the relationship between the two groups became closer because they both have members from Thailand, Lisa (Blackpink) and Minnie (G)I-DLE.

Currently, both Blackpink and (G)I-DLE have become top Kpop girl groups. Although it did not achieve the same global success as Blackpink, (G)I-DLE's position in Korea is still solid. (G)I-DLE is the first K-pop girl group in history to achieve 4 "Perfect All-Kills" with 4 consecutive albums.
Perfect All-Kill is a certification for the song that is No. 1 on the top Korean music charts (Melon, Genie, Bugs, YouTube Music, Vibe, Flo) under the Instiz iChart system.
