"Queen" Lin Wan, the leader of the top international hacker organization "Dark Night", disguised herself as a cowardly and incompetent ordinary clerk in order to investigate the truth behind the mysterious death of her best friend, and married Lu Yi, the president of the business giant Lu Group. This is where a contract marriage begins with each person's own agenda. Lu Yi needs a "vases wife" to stabilize the family situation, while Lin Wan needs an identity to get close to the core secrets. During the trials and games between the two day and night, a secret love arose between the two. When the fog of truth peeled away, they discovered that each other was burdened with a heavy past, and behind the death of their best friend, there was actually a huge conspiracy that shook the entire business world and the dark world.
