Chen Mo is an orphan earning a monthly salary of 3,000 yuan when the chairman of Tiansheng Group begs him to impersonate their missing crown prince, offering him 100 million yuan.
On his first day on the job, singer Lin Wan'er sneers at him, saying, "I hate rich second-generation kids the most." But he unexpectedly activates the "Super Spendthrift System": every purchase earns him a hundredfold rebate, and the more recklessly he spends, the richer he gets! While shopping like crazy and amassing a fortune worth hundreds of billions, he hides his identity and pursues the icy singer.
Just as the act turns real and they give each other their hearts, his identity is about to be exposed.
When the mystery of the real and fake crown princes is finally revealed, everyone is shocked to discover that the poor kid who ate instant noodles is actually a genuine heir to a wealthy family! From fake heir to true legend, he wins the most precious love and life in the most "spendthrift" way possible.
