I would have liked his being a vampire to play a bigger role in the series. a lot of the time if feels like an afterthought.
I really don't understand why her being his mom had to be kept a secret. Since nothing negative happened when it came out, it seemed like a contrived & pointless reason to create a misunderstanding that kept them apart.
I actually completely lost interest in SuJung when his true love turned out to be a woman. So boring. & he's such a whore too.
To be honest, I don't really know a lot of mangas where the story goes beyond the relationship, outside of mangas that are about already married gay couples trying to raise kids, so it makes me suspicious that they'll break up again, because it feels like we've jsut started a new story arc.
With long hair, he looks like that guy from the manhwa about the baker & the mangaka.
I really love how his unfortunate relationship with his father & learning about feeding or not feeding stray cats allow him to specially empathize with the vampire ^_^
