Singer Lee Chae Yeon took to the private messaging platform Bubble to call out RBW, the parent company of WM Entertainment. 

Lee Chae Yeon will be attending the RBW family concert, 'RBW 2023 Summer Fes - Over The Rainbow', in Tokyo, Japan this weekend from August 19-20. 

In light of the weekend's event, Lee Chae Yeon wrote to fans on Bubble,

"You know, I really put up with everything else?

But right now, I'm so angry that I'm writing this and deleting it and writing it again.

Whatever, let me be honest.

This RBW Japan concert, I really wish that they would be a little more considerate toward the staff who are managing and helping out.

It's been a burden on my chest.

I wanted to look nice on stage, so I personally paid to have my hair and makeup staff fly to Japan with me." 

Meanwhile, artists including MAMAMOO+, B1A4, ONF, Oh My Girl, ONEUS, PURPLE K!SS, MIRAE, and more will perform this weekend during 'RBW 2023 Summer Fes - Over The Rainbow'.
