so basically, many write BTS as 875, we also write ARMY as ami and the number 431 resembles the three letters A,M,I 875+431=1306, which is bts's debut day. And 875 - 431 = 444. The no. 444 represents a sign that you are following the right path WE'RE DESTINED TO BE TOGETHER!!! 5:43 AM · Dec 5, 2021.
