Lin Xia is a senior fan of Gu Chengyu. In order to get close to her idol, she successfully applied to become his assistant with her excellent photography skills. However, Gu Chengyu in reality is completely different from the perfect image on the screen - he is cold and distant, extremely harsh on his assistant, and does not even allow her to get close to him. Lin Xia gradually discovered that there was deep loneliness and pain hidden behind Gu Chengyu's indifference. He seemed to be escaping from some unspeakable past.
