Alright. This is a great piece of work.
This manhwa had such a different feel, different mood to it than most other manga that I've read. There's an air of sophistication in there.
You can thank the artwork with it's unique, almost western style to it. I can compare it to the illustrations you'd see in a classic book publishing. And it gets better as you go along reading the series. It certainly fits its British setting.
You can also thank the character development. Particularly with Ellie, who is an unapologetic, strong, fierce woman; one who grows with you as you read on.
It's a long story,
and it can be rather slow at some points. I can admit that it can drag on a bit. But if you don't mind the slower stories, I suggest you pick this one up. Maybe you'll grow to love it, like I have.
Anyhow, go read it!
