sure, there's some eh stuff in the show that i don't like, but i'll take it. i love this show, period.

concept: yes yes yes. i love microcosm environments in general, but this was unique. every character had a good amount of purpose. every stylistic choice from the actors to the hidden details- i WISH every kdrama was at this level.
execution: LOVED. and the twist- holy- I NEED S2 NOW!!!
pacing: smooth like my skin when i actually remember to do my skin routine (very smooth, trust me).
