Jin had recently announced the release a collaboration at BTS's Busan concert. He said, “I have a new album coming out. It’s not that big of a deal. It’s just a single. I was able to collaborate with someone I really adore. I have a lot of contents to share with you so I hope you enjoy them.” 

Now, Army has been speculating that the collaboration is with the British rock band Coldplay, with whom BTS had collaborated earlier for 'My Universe.'
