Cure Blood

This is a short, sweet, and sentimental manga. The two main characters aren't explicitly in a relationship, so if that's something that will turn you away from reading it, then be warned... However, despite that, it's definitely still worth a read (and they're very much in love with each other anyway). It's not phenomenal, but it's a good story to spend some time on and it will make you tear up. The art isn't bad either, there's no glaring errors in it. The more casual take on a vampire plot makes the story a lot more enjoyable, of course one of the main appeals for thevampire trope is the dramatic aspects of it and so turning that into something where they're just taking care of each other is very cute.
