"A guy and a girl can just be friends, but at one point or another, they will fall for each other...

maybe temporarily, maybe at the wrong time, maybe too late, or maybe forever." 

Hyoyeon and Eunhyuk have been close ever since the first day they met at SM Entertainment as trainees ten years ago. Despite the slight age difference and the fact that they need to keep up appearances on camera, they treat each other informally behind the scenes - spending time together whenever they can, joking around, practising their dance moves, eating meals. They are each others' best guy-girl friend. 

But as time goes on.. will their platonic feelings change? Is it true that they will fall for each other...? What if it's just one of them?

Will wrong timing cause them to lose their chance?

Will it be too late to save even their friendship?

Or can they make it to forever?
