To put it simply, there are spome scenes/aspects/themes/what-have-you in this series that are super, SUPER cute, just flat out adorable, though that's my opinion. The number of times I squee'd to myself is the sole reason I'm writing this review.
So if you like (what-I-think-are) really cute things, and want to watch a series with an intriguing plot structure, well developed characters, and enjoyable animation, this is more than worth giving a chance.
