On August 19, YMC Entertainment apologized to fans and reporters who were waiting for the members, stating, "Because of safety concerns, it was impossible to enter at the usual gate. The airport staff then opened up another gate for the group to use to depart. As many people gathered and paralyzed the airport, we came upon the decision to ensure everyone's safety in that situation, so please understand. We'd like to apologize to fans and other persons related."
