Jessica Sooyeon Jung and Krystal Soojung Jung are sisters, who have the best sibling relationship. Of course, they argue, fight, and hate each other at times, but by the end of the day, they make up and love each other. Jessica was forced out of SNSD and there were many rumors about her and she was hurt really badly. She had lost almost everything, but she knew that she would always have her fans, her fashion-business career, her parents, and most importantly, she has her sister who has always been on her side.

However, what would happen if her business wasn't doing so well and her fan base started to decrease due to the false rumors about her? Most important, what would happen to the Jung sisters if Krystal was to betray her older sister by taking sides with SM and SNSD?

Will Jessica ever forgive Krystal?

Is Krystal doing this to hurt Jessica intentually?
