On stage, the YulSic couple appear to be real and happy, full of skin-ship and love.  But behind the scenes, it is completely the opposite.  Kwon Yuri has been dating Jessica Jung after a year since their debut.  At first, the two were madly in love, always talking to each other and couldn't be away each other for more than a day.  Throughout the years, Jessica became more and more distant.  Every time Yuri brought it up, she would immediately get offended and walk away.  What will happen when Jessica loses the thing that is most important to her? And to none other than her best friend?
