Vampire Kisses...It's based on an American book series called Vampire Kisses.
It's a new series so there's only like one book out and, like I said, it's American, but it's super good!
You might want to read the books first. Not only because it'll help with your background knowledge for the manga, but also because it'll waste your time until the next books come out.
There's four books in the series.
The fifth book comes out in July and the second book in the manga comes out in September. XP
It's a long time to wait [especially for me and my friend] but, it's still a super good romance vampire story and it's funny at times, too. You'd like it.
