Let's go up high to the end of the blue sky. You and I together, forever together 

Chaeyeon just move to her new house and she didn't know that there is a ghost named Miyawaki Sakura who lives there too        

sakura loses a game and had to do a dare. guess what dare she got from her friends?

A story about how Chaeyeon had this odd attraction to sakura, when its normally her that enchants everyone to fall for her. 

Upon further inspection, Detective Miyawaki found that there were more to the burglaries than just the simple white feathers left behind at each heist.

Chaeyeon is sad because Sakura is spending all her free time gaming and not giving her attention, but one day she finds the perfect plan to make things return the way they were.

Tweleve teenagers never knew how much their lives would change so drastically since then.  How they wish they could turn back time before that one specific date. June 15. They didn't ask to be what people would consider them as "monsters".  But maybe thats what brought them together. But was it for the good or for the worse?
