Of course it’s centered around coffee. Have you even looked at the title and alternative titles? Lol And yes, those kinds of continued misunderstandings always make me want to tear my hair out.
I’m aware it’s centered around coffee but even with other books with similar features like stationary store, the tea, the cellphone aren’t that centered. Every conflict in this story is solved by coffee, she was getting hated by the upper ladies? Coffee. The wizards who hate everyone? Coffee. Every maid avoiding her? Coffee. The former grand duke who everyone is afraid of? Coffee. A EIGHT year old long eating disorder caused by trauma? Solved in a hour with coffee. She getting branded a witch? Coffee.
There you go! That's what makes this story different than the rest. It stands out to you, even if you don't particularly like that aspect.
I love the story but it’s too centered around coffee, I understand that’s her drive but the only plot is capturing everyone on her side with coffee. She fixed a literal 8 year eating disorder just with coffee, got wizards on her side who hates noble on side with coffee, got the old duke on her side with coffee, most of her conflicts is solved with coffee. It would make sense if this world was based in a universe of coffee addicts but it’s nothing but coffee. And the ml is just a walking misunderstanding, they added misunderstanding after misunderstanding when they can literally just say what’s in the thought bubbles. That’s literally the only continuous conflict.
