I think that this anime is very unique in its own way. And i like that kind of anime who is unique is the better one's (own opinion) i have seen many anime which have a simular kind of a story and yea i find that the anime is good, but its still a kind of same story as i saw before. I always keep that in my head. Is this anime story/characters as the same anime i have seen before.
Anyway, I think this is one of the best anime i have seen so far. I find this anime in simple 5 words. Funny and a amazing story! I find this anime to have almost everything i like: Comedy,deeply explained characters,good story,a bit of ecchi to make sense with the comedy,a good ending and a good beginning,romance and at last great animations and sound.
I give this anime 10/10 because it has those category's i personally likes and i love the everything with it. I even cryed at the ending. I have watched the ending 5 times now and i'm still crying. So to everybody who hasn't checked this anime out. You should do it in my opinion.
