[Spending spree story + pure wish fulfillment + everything is about enjoying life, no logic required + lighthearted daily life + multiple male leads + carefree romance + all the male leads are devoted to one partner + dating, but romance isn’t the only focus] Jiang Mengying was a corporate drone who had accomplished nothing in three years on the job. Then, one day, she heard a ding. Her tycoon System had successfully bound itself to her! With a black card offering a quadrillion in credit, she spent money in every way imaginable. [Ding! Congratulations, Host! You triggered a wealth bonus and received 2 attribute points!] [Ding! Congratulations, Host! Your influence has reached 5%. You have received a 5% stake in Xuanyin!] [Ding!
