There's a spin off and a sequel to this, but neither are translated on mangadex. And it looks like the Anime only covered half the stuff, and never got a second season.
It's a shame that this underrated series flew under the radar like this. It's easily one of the best romance and period piece mangas I've read. That said, based on the summary description, it didn't seem that good. I held off on reading this for a long time and now regret it. I would say at the very least, that this manga needed (and still needs) better marketing.
