My Collection of Victorian Romance Webtoon which contain more than 600 titles, so there is more than 10 lists (separation is based on status like complete english). You can see all of them >here<.
.
Because it's hard to track all active translations (official or not), I'm tracking only newest and adding here until I have time to sort them into proper list when I check if its victorian romance. Sometimes I'm not sure about series, so they can be here for longer. Like lady alchemist, I think maybe it's too modern? And there is no nobiles/royals?
