It annoys me slightly when they introduce coffe as a drink not just beans into the story and smh no one knows how to brew it. (If they introduced the bean and mc made the investment of introducing it as asking then maybe it works)
Since historically it was introduced to Europe by the turks in 16th century, the brewing method is still the same today (similarto euthipoan method made centuries before it), didn't need fancy Americano filters too be popular.
And they don't comment about the market of it or why and how it was already a served drink in shops, the market demand, or the quantity of import
I honestly like this manhwa but i can't help but be a little annoyed when the author makes everything too modern. And when the characters overexagerate . Like, i understand that you liked the drink, but it was a little too much
