This is my first review so please take it in mind.
Even though it was short, it was very nice to read.
I don't wanna make this long so here it goes:

Art: 9/10. The art is beautiful, so delicate. I love it.
Story: 7/10. Simple, I think it could be even better.
Enjoyment: 8/10. It has some funny parts that I like. It's enjoyable to read.
Character: 8/10. I also think they could be even better.
Overall: 9/10. It's alright, considering that it was short. The story and the characters are according to this kind of manga.

So...If you like to read a manga with a little bit of romance and vampires, read it.
