The art is nice enough. The storytelling is straightforward and easy to understand and there are no pacing issues.
But other than that, this story is nothing deep. It is a light-hearted story, and mostly about MC "inventing" coffee and coffee-related things. The romance element is not much, at most only 20% of the story. There's magic, but other than having "mages" using magic to invent machines for making coffee, it is not showcased at all and is only mentioned for formality. The villains are also not profound, their tricks are trivial.
It's basically just a "coffee! coffee! more coffee!" kind of story. Well maybe it will change a bit in the next chapters because the story is turning to the plot about MC's mother. But at chapter 73, the story is just that simple.
But anyway, this is a cute manhwa, and easy to read. 7/10.
