It amazes me of the high rating that this manga has.
It really shouldn't, yurifags don't have any measurable standards when it comes to quality of their beloved genre. As long as there's "fluff", "happy ending", "kissu" and "no males in sight", everything's a masterpiece. Things deviating from formula using those components will be met with opposition and varying degrees of bitching, no matter the story's execution*.
As for the comic itself, it's mundane and forgettable - easily could have appeared in Yuri Hime and wouldn't stand out in any way among the rest. Art is nice i guess, as far as level of pixiv doujins go.
*oh, some comments in "Purple Qualia" thread at some other place - in which specific part of your ass your head has to be located for you to actually complain about absence of "confession" in a series like that?
