My Little Vampire

This is a world where humans and vampires have found a way to co-exist: artificial blood. Still, it can't really helped that people would be scared of vampires because of their dangerous nature. Meanwhile, a man (uke) who is tired of loneliness (death of lover) decided to adopt a vampire child. OFC, he had needs so he calls in for sex service every night. What he didn't know is that the kid sees it and because the kid drinks his blood, he is growing up too fast. Will MC (uke) be able to see this vampire as a grown man when he was just an adorable little child yesterday?
