Just finished this tonight. Was pretty engrossed most of the way through, but the ending really flopped for me. Too many unresolved plot points, and not a particularly satisfying conclusion. I know its sequel bait but it would have been nice to have a bit more resolution.
Also they really did my girl Sae-Byeok dirty.
Episode 6 was great though. And yeah, turned the dub off like 5 minutes in.
