Ryu Changfu (Cha Tae-hyun) seems to be just an ordinary young man, but he has super "dynamic vision". When he was young, because of this unusual thing, Ryu Changfu was often bullied and criticized by people around him, and his young heart was hurt. Ryu Changfu hid at home all day, never leaving the house, and relied on watching TV dramas to survive. However, the world behind the screen is just an illusion after all. Finally, Ryu Changfu decided to step out of the house and see what the real society looks like. Ryu Changfu came to the Korean Monitoring and Control Center, but because of his personality, he ran into obstacles at work and was not happy with his colleagues. Fortunately, he met a doctor named Bingzhu (Wu Dasu), who became his strongest backing. With his special ability, Ryu Changfu was soon reused by his superiors. One day, on the monitor, Ryu Changfu saw a girl named Xiumei (Nan Xiangmei), and the wheel of fate began to turn.
