It's not fully uploaded here but you can go to Lezhin and read most of it for free there (you still have to buy a few chapters though but it's worth it)

those are pretty good as well but they probably won't be available for free soon:

http://www.mangago.zone/read-manga/winter_woods/ , http://www.mangago.zone/read-manga/orange_marmalade/. These are really really great webtoon but theyreso underrated. You can actually read it on webtoon also, I totally recommend these and hope you read it

Definitely read orange marmalade first though

Tomb Raider King 10/10 recommend

Wow I have seen all those webtoons manga

Ughhhh

I mean, you have about 2,000 titles in you're list so I guess it's impossible to recommend anything you don't know ;).
Maybe this one is new to you?
