Im also from a coffee oriented culture (which is why i always felt envious when no one else had to deal with heartburn or too sensitive of a heart from caffeine huhu). It just worries me coz as someone who is more familiar with the effects of coffee than tea, it rang warning bells when the wizard was a little too into it haha i mean, even the mc says he might overdose and they even had a lore about it causing madness. And having read duchess' 50 tea recipes, couldnt help but compare the risks that coffee has especially because the author even linked a foreshadowed danger hahaha

She made me smile right off the bat. She lives her life at her own pace but is intellegent about the politics around her and concerning her. While I'm frustrated by certain antagonists, her character isnt dense nor naive. She knows and she chooses to keep her peace.
My worries would probably be comparing it to tea since...coffee always whispers some resistence in my head. What if they overdose? Heartburn? I think coffee is way more particular, not just preference, but in effects? Or maybe im not so knowledgeable about coffee and think that its a way stronger drink than tea (and yeah, this is coming from duchess's 50 tea recipes and the general tea culture that im not even part of, just my own particulars with coffee and my acid reflux if it isnt alkaline coffee or diluted coffee)
