An arranged marriage between two of the capital's elite families begins with a life-saving act of kindness from decades ago.
Shen Huaizhi, the youngest senior diplomat at the Ministry of Foreign Affairs, accepts this "bond of duty" with calm composure.
Su Wanli, once a rising star in the legal world and now a deeply investigative journalist, resists this "emotional entanglement" with clear-eyed independence.
After their wedding, Shen Huaizhi seems gentle, yet steadily presses closer. She builds a wall between them: "Mr. Shen, please keep our relationship professional outside of work."
She never expects that he will take her resistance and distance as a silent confession. "Mrs. Shen, this is a marriage. We don't talk business between us!"
He advances step by step, weaving a net of tenderness and drawing boundaries with his power, gradually breaching the walls she has built so high.
In everyday life, his care is everywhere; at work, his help is always perfectly timed.
Amid the rules of their social circles, they stay true to themselves; in the whirlpool of love, they meet as equals.
In the end, their contract blossoms into a happy marriage, and duty deepens into devotion. Two proud, solitary souls draw closer, little by little. Beneath the neon lights of the capital, they write their own version of love at its finest.
