BTS has been feeding us SO well lately. We got J-Hope's mixtape earlier this month, and lately it seems like we've been getting non-stop BTS Run episodes and Bangtan Bombs on YouTube. So, ARMYs were completely caught off guard this morning when BTS tweeted out a cover by JK (Jungkook).
P.S. Look at the link... The Soundcloud cover URL has the words "songforarmy".... OKAY JK. I cry.
