From what i understand after reading is that as the first vampire i think it mentioned that he split himself apart which is how obtained immortality so ML and MC are two of the same whole but the whole family thing doesn't make sense to me either unless he was adopted or something, which would bring up with the question of who his father and mother actually are?
Okay, so question. Is the ML the first vampire, if so I need some answers. 1: Why doesn't he turn the MC into one himself? We know he made him human again. 2: If he is the first vampire, then how could his mom be killed by vampires unless it was like a long ass time ago, but he has a newer looking picture of him as a child and a women, if it is him.
