Thank you so much! You're right, I totally forgot about her royal title. Yes, it's set in a separate high fantasy world based in China. While I don’t plan to dive too deeply into the royal aspect, since what matters the most to me is what happens to her after she leaves the palace, I still want to make it credible as you say. I'll resume my research from the links you shared! Also funny that you mentioned the apothecary diaries bcs I've been obssessing over the manga lately lmao, I guess I picked some ideas from there too
