No I doubt it usually with plots like this the other person has to be dead for them to isekai to the world into their body so no worry (I only remember one story like that and it was complicated so hopefully not)
Oooohhh...what's the name?
Phew it took me a while to find it but there you go the name is Yasei no last boss ga arawareta
Oh and if you want mire recommedation ive got alot with this sort of setting but most people don't read it because it's not popular which is sad because they are all good stories
But I wonder how they die. I usually dont think too much about this, but they didnt explain and I feel sorry for the real-duchess :(
In the end she died without any improvement ..
Pretty much that's why they send people from another in an almost the same predicament so that they can try to change and as for how the duchess died as you know they were barely feeding her and the water they gave to wash up with was icy cold so she most likely died because of the bad treatment and the fact that she didn't speak up about it that's how it is
Omg, true. That's so sad D'':
What happened to the real-Duchess's soul? I'm so nervous to think she can appear in the future and the tea-Duchess's disappear or go back to the future/other dimension >__<
I get so confused about those things: did she died drinking? How about her body (tea girl real body)? Did the real-duchess go to the tea-girl body? Σ( ￣□￣||)
