In Tianjin and Hong Kong in the 2010s, Su Wan, a "red rose on the wharf" who was born in the city, reached a deal to "act as a couple" with Lu Chengyuan, the indifferent heir to the Lu Group, in order to pay off his mother's debt and get out of the quagmire of the bottom class, and accidentally got involved in the whirlpool of the wealthy family. She deals with Lu Minghai, who covets power, and the old man of the Lu family who hides secrets. She also has to deal with the threat of the "Xingsheng Gang", an underground casino force. From the turbulent undercurrent of the villa dinner, to the shocking life and death test in the hospital, to the head-to-head confrontation at the bidding meeting, Su Wan used the wisdom of the market step by step to not only help Lu Chengyuan uncover the mole and stabilize the group, but also allowed the two to develop sincerity from "trading partners" while fighting side by side. But when the "secret documents" behind Lu Minghai surfaced, the ambush in the old dock warehouse quietly unfolded. This entanglement that began with interests will eventually usher in an ultimate contest involving life, death and the future in the intertwining of love, hate and conspiracy.
