Kyuhyun has no idea when he shows up to pose for a very famous (and bad-tempered) photographer. He never imagined to end up working as Choi Siwon´s assistant for five frustrating, thrilling and crazy years. It all works until Siwon realizes Kyuhyun has become the focus of his life, a life that´s threatened when Kyuhyun actually leaves him to start a relationship with someone else. Even though it breaks his heart, Siwon realizes he has to set his beloved muse free since Kyuhyun´s happiness is his own happiness. But does Kyuhyun have to say something about it? Does he agree with Siwon´s choice?
