Even i got annoyed by their attitude.
With that kind of medicine which was so so so rare, they cannot even get it to themselves normally or anywhere even in the royal capital.
Also, its the dumbest way to ask someone who posses something that will save the lives of your love ones, and whats more, its the whole village.
Calling her witch while trying to get what you want is the lowest of the low.
To consider, MC is a Japanese that values attitude and respect, and he had none at all.
If you want to have the kind of medicine again to save your village, bring more Lolis.
If MC doesnt want that, let me take the negotiation instead, just bring more lolis...
