I see, I've seen it, some were good, and some were bad, i agree, they left some parts, i feel like it's both finished and unfinished. when they dragged the episode out, they could've use that chance to explain things like, why would the killer want to attack her? what is his backstory? so many details unexplained. Aside from that it's good ig.
I just watched the all the episodes, actually it's a good one for the least, it's been months since I've watched kdrama, and from my perspective its in between mid and good, and i agree by how you said they really dragged out the episodes hehe, it was actually good to end it with 12 episodes, and this is good for a kdrama starter, overall I'd atleast rate it 7.5/10.
