...you already have an idea of what my world is like. But the full story is... so much worse.

Before I came here, I'd never seen an elderly human before. I didn't even know they could live that long.

[While it'd be easy to think the climate may play a role in that, given Childe himself lived in a cold and wintry place, that's unlikely. And certainly he wouldn't be mentioning it if that was all there were.]

I know it won't make a difference. But I just... I can't just go on drinking human blood and starting over here like none of that ever happened. Since the humans of my world never got that chance. It's not fair.
