During a music show that every typical idol attends to, a peculiar relationship forms. Sistar and Exo are the fated two who will be thrown into this cruel reality in which they just so happen to cross paths ending up in a rollercoaster ride of confusion and selfish desire of a human's mind. Backstage is where the fans don't see, where everything happens.    

Exo's Lay has been admitted to the hospital due to his fatique of trips to China and back to Korea plus the studio he uses in China as well as Exo promotions, Suho, as the leader stays behind and watches over him for a night. Suho had to break it to Lay, that he had to live in reality.
