The issue is that the magical-fantasy (i.e. the world-building) is incredibly plain and shallow, romance (and all the characters except the protagonist) are never built upon, and the suspense is never followed up on. This last part is especially heinous, as it leaves the reader with questions regarding a lot of the plot. Answers are never given to these questions. All this set-up for a grand plot and nothing is followed up on. Nor are there really any mysteries. Instead, we're left wondering what the consequences of these actions are, and why some characters performed certain actions during the course of the novel.
Perhaps then, this novel is also a mystery? But no, there simple isn't enough substance in the novel to answer anything.
If you look at this novel as a "slice of life", the novel is merely acceptable. However, because the author goes through so much effort to explain things that add to the suspense of the story, this becomes a drama and not a slice of life. But none of the suspense is resolved, leaving the reader left feeling unfinished.
Perhaps this novel would have been great if the author was given another two or three novels to fill out the series. However, in the Afterwords, she says [paraphrasing], "This book has been adopted from the webnovel, but I added about 50% more content!" I shudder to think about how desolate the original work was.
The novel isn't completely irredeemable. The protagonist, side-characters, and their hi-jinks, are interesting until Chapter 4 (~45% of the book). At that point, everything falls apart. Had the author continued what she was going for initially, we would have wound up with a laudable-for-an-amateur slice of life novel. However, starting in Chapter 4, the author decided to not build up anything anymore and remove the interesting bits of the story, as well as making the protagonist into a dense idiot, thoroughly ruining all the previous good work that she has done.
I wouldn't recommend this book to anyone except aspiring authors for the explicit purpose of learning what not to do.
