OK, now this is an interesting manga. Firstly I thought it was another romcom slice-of-life manga but they added some things like his mother with vampire teeth sucking the blood of his father and the history of the backstory of his family. These things have kept us in suspense so I'm reading it. I would recommend it.
Art: It was pretty good so no complaints there.
Characters: They have defined both personalities of MC They are still pretty good, but I would have loved to see the more side characters' personalities. But in the future, I think we will get a better picture when they reveal the backstories of the MCs.
Story: As I said firstly I thought it was generic romcom slice-of-life manga but they kept the mystery about the parent's background and many things to keep us engaged in the story.
Overall it's a good manga I would highly recommend it. But I can say that this story takes us; we need to watch out for that.
