There's something wrong with Taemin - Minho doesn't know what. But he knows that Taemin no longer wants to talk to him, no longer answers his calls nor replies his texts.

There's something different in the way Taemin dances.

Taemin dreams of things. Things that come true, things that he never actually cares about. That is, before he dreams of Minho's death.

And while they were both struggling - Taemin running away from reality and Minho chasing after his sanity - they got paired up for a performance item. A couple dance. Their very last dance.
