A letter shared with BTS' fans, who are lovingly called "Army", the K-pop superband announced the #MyBTStory challenge in partnership with YouTube, starting on Friday and running through July 9, exclusively on YouTube Shorts. In celebration of their new album, 'Proof', dropping on Friday, the group is inviting the Army and all music fans to join them in the #MyBTStory challenge, reports 'Variety'.

Within the letter, BTS expressed their appreciation of Army's support over the past nine years and asked them to share their favourite memories from that time on YouTube Shorts, using the hashtag #MyBTStory. Soundtracked to 'Yet To Come (The Most Beautiful Moment)' or any of BTS' hit songs, the Shorts created as part of this month-long challenge will honor the connection that BTS have built with Army and music fans around the world.
