They wrote, according to the Facebook translation:"We are extremely sorry for our insensitive actions and use of blackface in our video while portraying Bruno Mars. There is no excuse for what we did and there are not enough words to explain how regretful we are. We are heartbroken to have hurt our international K-Pop fans so deeply. We love and care so much for all people of every race, sexuality, religion, and gender. We love all our fans and are so sorry to have hurt our fans in the black community. We understand now why our actions were wrong and we never meant to do harm with our video. We were extremely ignorant of blackface and did not understand the implications of our actions. We will be taking time to understand more about our international fans to ensure this never happens again. We hope that you will help to educate us on these and other issues so that we can become better people and better artists.

Thank you so much for bringing this to our attention and allowing us to right the wrongs that we have done.
