A charming 25 year-old man, who comes from a wealthy background, lives in a penthouse apartment and tends to eat too much.
I’m excited about this website!
Anyway, as you can see, my brain is not helping me today, so I thought I’d find some writing prompts.

So, using the above, we have an easy-going 33 year-old woman and a charming 25 year-old man.
The story theme is freedom. The setting, at least one setting, is at a museum.
Let’s start with the woman. We know she’s careful yet easy going. How does that work? (I’ll have to come back to that question). Let’s call her Jane and let’s put the museum in London. Jane is British. Jane Astin, who often gets teased about Jane Austen, the author? But she laughs and says, “I wish. I’d be married and rich by now. No Mr. Darcy for me, unfortunately.” Why is Jane in the museum? Jane is an authority on art and is trying to identify, for the museum, whether a new piece is legitimate. Jame is of average size, unsurprising light brown hair, and brown eyes. Plain Jane, even. She wears glasses, and is a vegetarian. Careful, in her work or when presented with new information, but in general easy to get along with, not stressed out or bitchy. She’s interested in the truth but not on a crusade. She has a greater interest in why someone does something than in making moral judgements. Everyone in Jane’s world gets a second chance – which makes her a potential doormat, but she’s careful to let only those persons vetted through careful observation close to her.

The charming 25 year-old man who likes to eat when he’s stressed, who comes from a wealthy background and upbringing, who is also an artist. He does reproductions and creates originals. He works in his studio, which is next door to his penthouse, which is in a fashionable part of London. His secret is that he’s broke. Art is hard to sell. At 25, he is not taken seriously by the art community, so he relies on teaching art classes and making reproductions. His parents were wealthy and then lost it all in a stock market crash. His family history is important, and he is sending any extra money he gets to his parents so that they can maintain the house – so he’s descended from some British aristocrat. His father was in the stock market, and now he’s in jail for insider trading. And his mother is trying to maintain her lifestyle while being ostracized by her peers. Our boy Daniel Percy-Grant, son of Aaron Percy-Grant, 21st Earl of Woodcock, is just trying to keep things a float. He’s desperate and when someone asked him to create a forgery of a Toulouse-Lautrec painting, he did. But he didn’t expect the painting to go to the museum. He just thought it was for private use.
How is Daniel like Mr. Darcy? Assuming there’s a casual built-in comparison between Pride and Prejudice and this story. I guess Daniel is a little arrogant.

So – the bad guy in this deal is someone who wants to put a forgery into the museum in order to do something, like cause the museum director embarrassment, cause a… when the forgery is put into the museum, the authentic painting is stolen, and sold on the black market for big big bucks. Daniel is doing the forgery but he is not stealing the originals nor profiting from the sale of the originals. He’s just a tool.

So – how does forgery tie in to freedom? Well, if Daniel is caught, he could lose his freedom for being not interested in what his paintings were used for. Jane could lose her freedom because she’s given Daniel a second chance? or she’s somehow implicated in the scheme. Or something internal. Freedom from financial troubles? Jane is not wealthy either.

Obviously, Daniel and Jane will be going after the real bad guy in order to clear Daniel’s name.
Which would illustrate Jane’s vetting of Daniel in order to let him be close to her (her carefulness hidden in her easy-going nature), and once Jane is on Daniel’s side and vice versa, then they can go after the bad guy. Or they won’t succeed in capturing the bad guy until they are on each others’ side. It’s that change for the better in order to qualify to win thingy that is inherent in character-driven stories.

And we need a bad guy.
