To save her bankrupt family, Su Wanwan is forced to sign a contract marriage with Lu Zhiyan. What she doesn't know is that this transaction conceals the feelings he's kept hidden for three years. As one scheme after another unfolds, from her best friend's betrayal to business traps and the shadow of the mysterious organization Nightingale hanging over two generations, the couple go from cautiously testing the waters as spouses on paper to allies working side by side to unravel the plots.
He takes a knife for her; she digs up the long-buried truth for him. With every clash, they tear away another mask and uncover Nightingale's shocking plot to manipulate business wars, as well as the tangled past between the Lu elders and the organization. From a hospital-room farce to a London manhunt, from a birthday banquet scandal to a standoff at a factory, every scheme eventually falls apart. The contract has long since expired, leaving only the warmth of his hand and the resolve in her eyes.
It turns out the best kind of fate isn't a promise written in black and white. It's the certainty that, amid blades and danger, you still choose to spend the rest of your life with one another.
