Jessica stands there on the huge stage, lights dimmed. Looking down on her pretty shoes, her sweaty hand fidgeting with the microphone and the other pulling on the hem of her puffy white dress. She has always been nervous before doing live shows, but never as nervous as this one.

It's been a year since they've done a live performance of One Year Later. And now on this Christmas Eve, suddenly their people arrange a performance for them in a Christmas concert. Jessica was opposed to it at first, but she had to agree, anyway, since it's already done and she had no excuses.

She doesn't know why; they meet in the company everyday, do concerts together very often, and sometimes they even star in shows together. But being on stage together, just the two of them, singing their duet?

Jessica just can't face Jinki.

Could it be that they met the right person on the wrong time? Jinki and Jessica can always wait, but can they do that without hurting each other, other people and themselves?
