If you're looking for a romantic drama or a mystery/thriller drama, then look somewhere else. This felt more like a meditative exploration of what relationships can look like. I personally loved it. I loved that it was a wholly mature, no emotional melodrama BS that kdramas are known to dish out on popular demand. I wish they delved more into the backstory of NM agency instead of being this shrouded in mystery organisation. That would've added more depth to the story. Other than that, I loved the acting, the cinematography, the story, and most importantly, the framing of the story. Its not always that we see mature, muted, understated kdramas, and I truly think we need more of these.
