Choi Choi Siwon said on the 24th, "I saw a controversy caused by the incident on Twitter. I sincerely apologize for the disappointment of the act, which I did in the hope that violence and confusion would calm down. "
But on the 25th, one of the Choi Siwon fan clubs in China announced the closure of its SNS account, which seems to have posted a second apology.
In this public apology, China fans are reported to be showing signs of boycotting Choi Siwon's activities.
