The National Para Games Group has posted an apology on their website to apologize to JYJ's Junsu and his fans.

On October 8th, Junsu was set to perform as the finale stage at the opening of the 32nd National Para Games - Gyeonggi Province. However, many fans had problems with Junsu's final stage, starting from the lighting of the stage up to the way his stage was left out of the broadcast. It is said the cameras were packed up before Junsu appeared on stage and thus, Junsu's portion took place after the filming had wrapped up. To answer the fans' rising anger, presumably, the chief officer of the National Para Games uploaded the following apology and tried to clear up some of the misunderstandings.

I'm very sorry.

As the chief officer, I apologize to everyone for not handling the 32nd National Para Games' opening ceremony on October 8th with ease, causing concerns in delay and order maintenance.

Also, I apologize to Kim Junsu (XIA) and all the fans that came from all over the world early in the morning.

I will reflect on this and make sure nothing like this ever happens again.

I will give you an explanation pertaining to JYJ's Kim Junsu (XIA).
Unaffiliated with the radio�broadcasting, from the beginning we chose Kim Junsu (XIA) as the artist that would decorate the ending (finale) stage because he is popular and famous, we directly recruited him from his label C-JES. His label C-JES made a difficult decision in letting him appear even though there was short notice before the event because the Para Games was a meaningful event.

During the recruitment process, we recruited JYJ's Kim Junsu (XIA) from his label CJES through various steps in event planning. During the recruitment process, we confirmed his attendance by sending�him�information on the meaning and purpose of the Games, as well as the event schedule, and came to a mutual agreement. Also, we reached an adequate agreement about the opening program while we were discussing his recruitment. Two days before the concert, we received his performance music to heighten the quality of the performance. We set up the spotlight memory settings and VJ video separately, and took the lighting, sound, camera, and all other systems to the finale stage.

On introducing Kim Junsu (XIA), the label agreed two days prior to the event that following the live broadcast, Kim Junsu (XIA) would be introduced after the closing ment live radio broadcast, and Kim Chang Ryul would introduce him as the broadcast MC. Before Kim Junsu's final stage, the contents were agreed with the label on the point of when he would appear on the stage.

On the promotional items, his recruitment was not confirmed until there was only a short period of time left before the event, so his name was not included in the original promotional material. However, later promotional material and cards were created with his inclusion. After the conclusion of the after-meal event, after the departure of the main guests, there were many empty seats remaining, causing a bit of chaos. I apologize for not thinking that such a situation could occur, and apologize for causing discomfort to the guests. I have warned the security team to sincerely apologize to the CEO. I believe that the camera cleaning scenes that some guests saw was because the KBS team moved their cameras after the main event (KBS only filmed the main event). The celebratory event was filmed by us, and I will tell you that we did not miss any footage up to the very end, including Kim Junsu (XIA).

However, I apologize again for not giving detailed information on the entire situation. You may corroborate this information with the C-JES label. I thank C-JES and Kim Junsu (XIA) for attending the Para Games with meaning and interest even with their busy schedules, and I am very sorry to have caused a disturbance to everyone who participated in the event.

However, the apology seemed to anger fans even more. Many fans wondered if the apology was really from the head officer, as it was uploaded onto a free board where anyone could write, and also could easily get lost. Some fans even pointed out that C-JES was not a label, but an agency, and demanded a more proper apology. Many international fans flocked to the website in support of Junsu as well.
