Billionaire short dramas

Money is the plot here. A tycoon pretends to be broke to test a fiancee, or a waitress signs a deal that lands her in a glass tower full of relatives who despise her. The joy of these stories is watching rich people underestimate someone, then squirm once the bank balance, the secret or the marriage certificate comes to light.
