I got into this series without knowing anything about it, author and plot, and overall it was a very enjoyable read with a very slow paced romance(if any). There were many loose ends that were completely ignored but it wasn't a big deal until that ending.
If you are going to read this manga, please note, you are going to read a series that throws away the suspension it built for 200 chapter on the last few chapters with a very 'makes no sense' ending.
