On June 26, Sean challenged BTS to fulfill the mission within 24 hours. He also posted, "Chinese fans of BTS have already sent 10 million Won ($8,927 USD) to the Seungil Hope Foundation on behalf of BTS' V and Jungkook. Thank you sincerely."
It seems BTS did respond within 24 hours as their official Twitter posted the certificate proving their donation below. The message says, "We've come to participate in the Ice Bucket Challenge after Sean tagged us. We're very happy to join in on a great cause, and we hope more people show interest through our participation. Thank you."
Good job to BTS!
션 선배님의 지목을 받아 아이스버킷 챌린지에 참여하게 되었습니다. 좋은 일에 함께하게 되어 정말 기쁜 마음입니다. 저희의 참여로 인해 더 많은 분들이 관심을 가져주셨으면 좋겠습니다. 감사합니다. pic.twitter.com/fKCxdyDQQd— 방탄소년단 (@BTS_twt) June 27, 2018
