I constantly forget that this girl is such a hardcore otaku that her brain works on a whole other level.
She still cute though and that is what matters... isnt it?
The pacing of this manga is really curious, it has a standard normally but at certain points or at certain events the author "cuts" parts and just goes for the conclusion or just goes progress to another event, the funny thing is that even if i notice these changes they haven't really bother me (much at least, in the worst case) and he has maintained a good consistency of progression that you just get lost in the fluffy of the story.
Now i could say that at this point in the story Wakana's development may seem a little slow, he still an amazing boy and has more than once being an amazing person and having reached new conclusions about his life, but let be serious... the matter we all really care is when these two will hook up and "officially" become a couple, and in this matter the only one with true development, at least consciously, is Marin. But i am not really complaining i am satisfied with how things are now, but i would say in 10 chapters or so the author will need to progress Wakana in that department.
