I intend on writing a fan-fiction for the Black Butler/Kuroshitsuji anime series, that takes place a little later than its current Victorian era time frame. We're looking at...a rough range of 1900 - 1910. I know dating technically didn't happen the same way as we refer to dating back then. However, we're dealing with the characters of the Shinigami/Reapers, who tend to be just a bit ahead of the current times.
What I'm looking for specifically is what the intended friendly couple could've possibly had to do back then if dating had gone a little more along the lines that it does now. (I.e. Boy and Girl just want to go out for a nice, legitimately fun time.) What might have been available? What was there to do aside from dinner? No funny business, as the girl's...er, "parents" will be at home waiting up and watching at the window. So it has to be kept innocent fun.
I've tried looking up "Dating in early 1900s/20th century London" and "Activities (same time frame here)" on the almighty Google. The only thing that results tend to be children's activities or the usual idea of sitting in the parlor under the parental supervision. Again, I do understand that this was more how things were actually done, but the characters, like I said, tend to be a few historical steps of their time. Victorian England setting, and in one OVA, they're seen working in a very modern-looking office building and using modern day-ish equipment.
Any help would be appreciated. This is still an epic community that's helped me many times in the past. :D
