After the tragic death of her father, Xu Manzhen, a wealthy girl, fell into ruin and became a salesperson at the perfume counter of Yong'an Department Store. One day, Cheng Shaojun, a man who claimed to be a banker's son, appeared in front of her. He was elegant and calm, but he was almost paranoid about perfume. He approached her step by step, with calculation hidden in his gentleness.
And his true identity is Lu Chen, a military agent. A mixed-race orphan, burdened with his father's injustice and the kindness of Master Qi, was ordered to track down a list of Kou Island agents that could shake up the underground forces in Shencheng. The list is hidden in the Xu family, and Xu Manzhen is the only key.

"If I hand it over, we will all die."
In the spy mystery where lies and truth are intertwined, Lu Chen must choose - to be loyal to the mission, or to be loyal to her? And can Xu Manzhen find a way out between the hatred of country and family and the passionate love?
