Need money? Fair. Going against the royal family? Not a great idea. Politics are a whirlwind of their own. Becoming a courtesan? Eh. You have an income, stable housing, and influence when you get more exposure. If you get labeled as the party "at fault" by popular opinion, it could damage family image and future prospects.

On the other hand. Because the prince made himself look like a total lover, I think enough public pressure could be applied for consequences. Throw the guy off his horse and tell him to try again when he's become 4 years old at least. Get compensation for the broken engagement and any other stipulations.

Except. This. She's not got the most common sense, but dude. Really? Just because you're jelly and bitter, you're going to let her believe that she's working to get customers? At least she's being straightforward. Dude just going to dawdle around and take his time? Calm down bro. Stop treating her like a foal. She may be a bit behind with the situation but how can she know if no one tells her?

End long winded thought. Apologies.
