Yeah sure, kimonos as formal wear it is.

We should totally do that. Sibling rivalry could add another layer of drama to the whole thing. And drama is always fun. And I kind of have a thing for awkward love triangles.i

I like the ideas for the kingdom. I have my own ideas for a couple of the areas in the city to add to the drama. A red light district, because those are always fun. Maybe the sibling trying to take the servant away from the prince could bring one of both of the characters there. The other one is some sort of thieves district. Somebody from there could try and assassinate one of the royal family, or our characters could get lost in there or something.
