Harvey was just a normal human, raised a single child to unremarkable parents who passed away when he was almost 21. Then when he was 23 he met Zubenelgenubi.

He met a man with a strange name at a bar one night, and became instant friends. Harvey wouldn't've minded something more, but it seemed to him this man wanted to only be friends.

By god was he wrong. But it took about 10 years for him to realise their attraction was mutual. And one small confession that his friend was actually a demon in a human disguise. Harvey didn't really mind.

Once they started dating, and he was in even closer contact with Zubenelgenubi, Harvey started noticing that he hasn't seemed to age much these past years.

Once realising this, he started to document and research more, becoming utterly fascinated in the effect of long term exposure to demons, and, if he can ever find one willing to talk to him, angels.

He and Zubenelgenubi dated for 7 years, before getting married, and they've been husbands for another 11 years.

He doesn't think he'll live forever, but he does think he'll probably live much longer than humans usually do, and honestly, he doesn't quite mind that. He doesn't have many close friends, nor family, so all he really has is his little demon family anyway.

He occasionally wears a thin pair of red reading glasses.
