Many times the day just passes and you forget about the importance of who's around you. That's you, Celine. You were a trainee in SM but subsequently failed the final test for a selfish reason. The last goodbyes from your friends(SNSD) was "Good Luck!" and "We'll always keep in touch".But that wasn't the case they(SNSD) forgotton you. Because you make them to. But not too long later, you managed to gain a position in Acube which allows you to train Apink and prepare them for debut. But when one day you got abducted all you can do was wait for help. SNSD and Apink gather on a mission to save you. But is it too late?

"I have once died, and I rose up again. But today wasn't the case. The Death Doors I longed for so long is finally opening up.I finally understood why the day ended without you." ~~~somethingfromyworld

Apink knew nothing about your past with SNSD nor did SNSD know that you are part of behind the scenes team of Apink. You can only know to follow your heart. The abductors seems to know you more than others should have known. You are only given a change to call your old and new comrades for help. They are the only one's that you are allowed to call and given only a few days deadline will they pick up or even come to save you?

All the unknown secret spills out unintentionally. Hide it or open your heart?
