Going to reread since it's over now, but this is the best manhwa I've ever read, right next to Bastard on Webtoon. I like how it doesn't really have a single defining genre, just a captivating story and great art...it actually inspired me to want to try digital art bc holy shit koogi did it all on PAINT TOOL SAI? One flaw though: I really wished it had a completed/proper ending...
