The fact that all these chapters are only from vol 1 is insane to me. This one was written amazingly well. The last few chapters of everything playing out was absolute cinema. I'm glad I waited for the batch uploads before reading it all at once.
If they decide to end with the next chapter, I'd be 100% fine with it. But if they continue to adapt the rest of the volumes, I'd also be 100% okay with that. As MostlyHumanTL said, how it is executed that matters, not how original it is. I've read plenty of exiled/revenge manga/manhwa and this one was one of the best, if not the best, series I've read so far. Even if they go to generic fantasy stuff, I will be fine with how well written all these characters have been.
