Is the creator of this manga Russian?

lol no. The creator, Haribo, is korean and the original language of this manhwa is also korean. It's just that a russian scanlation group is really fast in scanlating this manhwa (the russian scanlation usually comes out a few days after the original in korean is being released) so hence you can see it spread around here since it's more accessible than the korean one.
You can have a look at the official platform where the manhwa is being released if you want,

It's not that they're just fast. If END (who posts and translates this) would want to she could release all 20 chapters. She already bought them. It's just that she respects and considers the well being of the artist. Most of people keep forgetting that this is a weebcomic. If no-one buys it than the artist is at loss. That's why END posts only chapters that are already unlocked by artist and free for public :)
Someone in Russia is just selfish and doesn't care about the person who pours his/hers heart into this piece of art. And creating something like this is shells lots of hard work. :/

You're right and I fully agree with you on this. I may have worded my post badly but I also didn't mean to imply that the russian scanlator is doing the right thing by uploading their scanlation so quickly after a chapter is being released. Sorry if my post leaves that kind of impression. Believe me, that is not my intention at all.
I only wanted to explain why the raws that being spread around here is in Russian but well... I guess I'm terrible at explaining it... :|
