This manga isn´t very popular, and I totally understand why. If you find this manga by chance or if it is recommended by MAL (as it was to me), don´t waste your time, read something else. Anything else. So here goes my review: Story - 3 There really isn´t much story apart from what is in the MAL synopsis. And yes I know it´s short, but I red even shorter stories that had some sort of substance. This manga is not one of them. Girl meets hot wolf guy and sleeps with him. In the three remaining chapters they take turns being jealous of each other. That´sit.
Believe it or not, one shot is even worse. Pathetic girl with no self-esteem whatsoever clings to random boring vampire.

Art - 5
I´m no expert on art (also I´m no expert on any other topic, but hey), it was okay for 2000-ish manga I suppose. Not really my style, but okay, I guess.

Characters - 3
Just awful. Blank slate main girl with no personality whose only role is being a damsel in distress. Wolf guy who is borderline forcing her to sleep with him because she is too pathetic to resist. In one shot girl who has no self-esteem whatsoever and is overall very pathetic. Boring vampire.
Side characters are very unimportant and all look the same.

Enjoyment - 4
I red worst things but not by much. I suppose it´s better that working (which is the only reason I actually finished it).

Overall - 4
Why does this thing have sequels?
Anyway, I would recommend finding something better to read than this.
