Fans have weighed in on the situation.
Koreaboo
Recently, THE BLACK LABEL, home to ALLDAY PROJECT, was accused of leaving out one of the members.
The group posted the track list of their upcoming mini album, ALLDAY PROJECT. Each letter stands for the member’s names: A = Annie, T = Tarzzan, B = Bailey, W = Woochan, and Y = Youngseo. Netizens immediately noticed that the only member without a solo or sub-unit song was Youngseo.
THE BLACK LABEL Accused Of Leaving Out ALLDAY PROJECT’s Youngseo
Now, “proof” of the members of the group allegedly mistreating Youngseo has gained attention.
Youngseo was initially announced to be a debut member of ILLIT, but left before the group officially debuted.
The group had a very different image than ALLDAY PROJECT, which left many surprised by Youngseo’s inclusion. A clip from a program where the group talked about Youngseo’s addition was posted on X, and was alleged to show Annie and the other members “making fun” of Youngseo’s dressing habits and behavior.
I feel really awful about what happened to her. She didn’t deserve to be treated like that, not even in an interview. u could see how sad she looked… I honestly don’t understand why the members of her own group talk to her that way. Their behavior is seriously disappointing https://t.co/6bdhewoOpq pic.twitter.com/LjyFYOd1Jc

Some have also brought up instances where the four members did things together without Youngseo as more “evidence.”
Where is Youngseo?? They are making it obvious rn… Leaving out Youngseo again. Their group dynamics is a joke lol. First Travis scot concert and now going shopping without her. I know Ot5 preachers will defend this too saying she might be sleeping, she don’t wanna go blah blah. https://t.co/NRsBpzYBJF

However, fans in defense of the group have stated that the clip of Annie talking about Youngseo wearing pink actually was from a segment where they all had to “diss” each other, rather than her being picked on. Additionally, fans reminded that Youngseo chose to debut in the group, and that their relationships are not just what is seen on the surface.
“i don’t understand” yeah maybe because you don’t know the context ??? it’s not an interview, it’s a game. if you think that’s horrible, you haven’t heard what she have said about woochan because it’s just a diss game and that’s what closed friends do https://t.co/ovLAmdnfhK
