It had its ups and downs but overall this is definitely one of the best webtoons out there. Beautiful art, interesting story, great comic relief, and realistic characters that definitely are not perfect but try their best anyway. There is romance, there are strong and heartbreaking themes of discrimination and prejudice (toward vampires, but relatable to real life examples like racism, et.), and more than anything, it was a story of friendship and unconditional love.
The story of Ma Ri, the vampire who just wanted to be loved and understood in a world that still hates and fears the vampire race even after they are no longer a threat, is sweet, sad and full of hope. Her friends are all likeable in their own way-- I particularly liked White Hair (whose name I could never remember--actually, Korean names are just hard for me) and the jealous blond haired girl who is not as terrible and mean as she likes to think she is. Jae Min is interesting too, and learning about his past really helps you understand him better, though for a while I was really ticked off at him despite that. Actually, there's a point for all the characters where you want to yell at them to stop being stupid and get over themselves, but that just makes it better when/if they finally pull themselves out of that rut and figure things out.
So yes, it's sweet, sad, funny, and the loose ends were tied up quite nicely in the end. It's the kind of story that leaves behind a pleasant hopeful feeling that even though things might get hard, there are still good things to appreciate in life and there's always going to be something to look forward to.
