They were asked for proof or why they said that about Chuu and this was their response
"For a few days after the announcement, the agency was told to provide evidence for the reason for Chuu’s removal, and articles were published with information such as “Chuu is not that kind of person” and “the company is the one doing harm.”
The fan notice posted on November 25 at around 5 p.m. KST was an announcement from the agency explaining Chuu’s changed course of action and the reason for her removal to fans and those who support LOONA, and it was not an exposé.
It is of course natural to explain the reason for her removal, and it is the rights of Chuu herself and the staff who was harmed to provide the truth or evidence of this.
Regarding the relevant facts, if there is something unfair or anything that should be corrected, this is an issue that the people directly involved should reveal."
Basically trying to play innocent wtf
