You'll need to give me some more details here. What's the letter that is supposed to arrive? What's the context?
i think they're talking about the nobility letter, which im fairly certain is 3 days
The letter that the servant says she will send when the manor is ready to live in. She won't let me enter the manor.
Oh, I see! You must advance to the next chapter for the manor to be ready. It's not a matter of time spent, in that case.
