It doesn't help that, no matter what subs you're watching, they're all bad in their own special way. Send up a flare if you need help, plus you can ask questions at theuntamed_mdzs.

I did find several things a lot clearer on rewatch, partly because the drama's structure means the first two episodes drop you in the deep end, and only make sense after you get done with the very long (but pretty!) flashback.
