First time I have a situation like this. All categories are 3/5.
I will update in the future, I will continue reading for now.
Writing Quality: 3/5.
Stability of Updates: 3/5.
Quite satisfactory. Few chapters and shorts for his releases. I'm not saying that I don't like short chapters, I prefer them over long ones.
Story Development: 3/5.
The story is classic and is based on the relationships of the various characters. So far nothing exceptional has happened. It doesn't bore but it doesn't make you want to read the next chapter right away.
Character Design: 3/5.
I like characters. The rating is more a 3.5. I find it slightly annoying how relationships are born in this story. They all seem to be born out of nothing.
World Background: 3/5.
Classic world, history in a school. Description of the places quite simple but being short chapters it certainly cannot dwell too much. Furthermore, being the real world there is not much to describe. So why 3? I would like a description that is not too detailed, but at least that makes you understand the environment.
In conclusion, do I recommend this book? Yes, it has potential, but for now it is not very developed.
