Gu Yechen is a ruthless, suspicious corporate king who wields power with an iron grip and believes that control is the only truth. No one has ever interfered with one of his schemes without paying the price. To deal with pressure from his family, he needs an absolutely obedient “contract wife,” offering her immense wealth and his protection in return.
Lin Wei appears to be a kind, fragile college student, but in truth she is a top assassin known by the codename “Nightingale.” She also has a gift for flawless voice acting, especially when imitating men. To save a loved one, she signs the contract, puts on a timid mask, and becomes a docile canary in his cage. By day, she is a sweet-voiced contract lover who depends on him, satisfying his intense need for possession and control. By night, she is a cool-headed, ruthless shadow operative, carrying out dangerous missions that quietly intersect with his world.
With her flawless voice and acting skills, she navigates her double life, treating him as the most dangerous target she must overcome. Gu Yechen gradually becomes captivated by her gentleness and dependence, but his sharp instincts catch the fleeting chill in her gaze and the tiny inconsistencies that make no sense. Driven by suspicion, he closes in step by step, scrutinizing every inch of her disguise like a hunter. Under his dangerous probing, she walks on thin ice, repeatedly surviving by relying on her quick thinking and acting skills.
Then a deadly assassination attempt on Gu Yechen nearly exposes Lin Wei’s identity. The truth tears everything apart, leaving them in a crisis far more complicated than love and hate…
In the end, can she escape her fate and return to the quiet countryside she longs for? And after learning everything, will he destroy her or give her back her freedom? This dangerous game that began with a contract was doomed to have no winners.
