Okay, I finally realized why its kind of hard to read this series. Its too sharp. As in the drawing style, not the image quality. Everything is so pointy, and it hurts the eyes to read, leave you exhausted.
The lines are thin, lightly colored or barely outlined, making it hard to distinguish the forms of the characters. It is highly detailed, but without solid lines, its very tough on the eyes. Not to mention the lines need some anti-aliasing being all blocky.
This is like the typical shoujo-drawing style, but stretched to a 11 in terms of soft lining.
