Wasn't it that the human would die? And I can see why that rumor would spread "Don't drink the blood of the human you love because they'll die" when it actually turns you back into being a human. Meaning less vampires, which the overall vampire population obviously doesn't want lol
I think this is like a basic subconscious that wants him to be as accepted as possible by other people, which is why it's saying it wants to be like his friend.
Thanks for the work Allen!
I don't know how the author is this clueless but for a person to even start speaking coherently they need around 70 IQ, which means Mu has at a minimum 1400 IQ, which makes no fucking sense.
