Go to weverse and write a post using #to_bts, the posts will be printed into letters and sent to BTS. They are aiming to do "the most longest letter in the world" and when they have enough letters the members will read them. You can write them from July 17th -> Aug 8th
may be a similiar event like BigHit had done for TXT. They’ll give us specific span of days to write a letter to @bts.bighitofficial via weverse and it’ll be printed inside the booth, folded and will be given to the members.
