Well, this series, in my opinion, went a little downhill after around the first ten volumes. Ill go ahead and get to the point:

The bad things:
~Most of the "story" was just about what you would find in any romance manga, except they make it so repetitive that it feels like you have already read it.
~Had the same old "ecchi" misunderstandings, but had them repeated every other page, and also had the misunderstandings barely every resolved.
~Had an unnecessary amount of drama, even for something so small and insignificant that you would not have even noticed it normally. That may be alright, but the things that the drama is about do not even advance the story. Hell, sometimes they do not even relate to the story at all.
~Also, they make it seem like talking to anyone besides your girlfriend/boyfriend is a disgusting offence that means you are cheating on someone.

The good things (I know, how can I write those after what I said above...):
~It depressed me, you may be thinking "wtf, why is that a good thing?". Well I will say this, it is hard to find an manga like this that can change your emotions. I may not have always felt connected to the characters, but this manga would make me feel happy at some points, and at others it would make me feel extremely sad. I actually felt like I could understand how the characters felt at some points, (as long as it wasn't the pointless misunderstandings and other stuff that is mentioned in the bad section).
~It had some pretty amazing endings to volumes, they always left you wanting to read the next one. Lot's of series I know leave the volumes off at a boring spot, who would want to keep reading that. Going back to what I said above though, the endings may be good in the sense that you want to keep watching, but they did not always relate well to the story. This one left every volume off at the perfect moment, forcing me to keep reading it.
~Lot's of funny characters for a bit of comedy to relieve some of the tension.

Well, sorry if any of my thoughts contradict each other. Also, thank you for reading this, if you hate this review, lemme know.
