Su Ruanruan was "thrown" into Lu Chenyuan's group as an intern when she came of age. Her lolita appearance made her a soft persimmon in the "workplace palace fight" - green tea colleagues grabbed credit, scheming executives set traps, and even the hidden "remnants of the previous dynasty" (the former president's old department) wanted to use her to bring down Lu Chenyuan.
She didn't have a golden finger, but she relied on the "decision-making cards" she played as a child to blindly defeat the game. She always mistook "palace fighting" as "playing house" and misused slang to make trouble (saying "taking the blame" as "carrying the tripod" and "laying down" as "retreating").
Lu Chenyuan regarded her as a pawn, but he was moved when she failed to protect him time and time again, and he felt distressed while taking advantage of her; she relied on him, but was in a dilemma after seeing his ambition clearly. In this "palace fight" under the guise of the city, did he win the world in the end, or did she win him?
