... according to the spoiler in the last chapter...I'm assuming that since the gun was in jk's hands, he stot Jimin, and after that j hope shot himself
or
since j hope wasn't going out, Jimin snatched the gun from jk and shot j hope, to this, jk shot himself and afterwards, Jimin lived with taehyung.
or
Just like taehyung appeared suddenly, maybe the other friends appeared too. maybe after Jk shot Jimin (according to the 1st prediction), yoongi shot Jk and j hope.
more predictions can be made. the end was left in a cliffhanger.
Neither have I talked to the author personally nor do I know the ending.
It was just a prediction.
