There does seem to be a novel, so spoilers are out there.
Here's a tip; either copypaste the translated title or the original korean one, put it on google, and add "novel spoilers" after it. If there is a novel, 99% the time you'll find a link to the novel updates forum. Often times people share spoilers there.
I personally don't want to see spoilers for this series at all, so besides looking at the first and second novel covers, I didn't check out anything. You're free to do so yourself if you wish to though.
Hey bro, chill, no need to get so offended about it - there's a lot of people who genuinely don't know how to do that, so my intent was just to share in a genuine matter, I wasn't being sarcastic or mocking. I also sometimes like to ask for spoilers, but I tend to specify what spoilers I'd like to get, bc the forums aren't always organised or easy to skim through, or I just don't care enough to bother. Just, if one is looking for general spoilers, looking them up is often the fastest.
Me saying I prefer to not be spoiled for *this series* specifically was just to express why I didn't read further than seeing the covers on the forum - sometimes I do go through them and then make a new comment or reply to someone with them, so yeah. It's absolutely nothing personal, was simply trying to be helpful ╮( ̄∇ ̄")╭

Need spoilerssssssss. If anyone already knows the future events, feel free to comment some spoilers here!!
