Let this be a warning.
This manhwa has a fairly interesting plot that got me hooked instantly. The author has a unique presentation that I find refreshing in a sea of genericness. That being said, while the beginning and middle were done well, something changed. The best way I can describe it, it's as if a sculpter crafted a masterpiece, only to take a sledgehammer and smash it into oblivion. Finishing this series felt like a grind or an endurance race. But having already invested roughly 200 chapters of my life into it made it hard to leave unfinished. The climax felt completely rushed and left me angry/disappointed for having viewed anything prior to it. I'm left with the impression that the author of this series must be spiteful or angry about something in their life to have ended the story this way.
TL;DR this had the potential to be a good overall story but the author took it off the deep end
