After yoongi serves a rather long sentence and gets out a few years later for evidence not being enough, he meets Jimin and things start to fall into place. After falling for the boy he starts to realize this kid is the reason he went to prison. The man that Jimin thinks he killed wakes up and tells the truth about Yoongi not being the one who hit him and knocked him into a coma, will Yoongi turn Jimin in, knowing he did it? Or will he forgive Jimin and the case go unsolved? What happens when JK remembers that it was Jimin and decides he wants revenge?
