It probably wasn't dumb writing. Watch that scene again, after hearing that Doo Shik knew about the stack of files,…
it wasn't coz she asked him about what tipped him off and seemed surprised by his response. and even if it was intentional, it's still dumb coz the guy she was tryna work is an elite black ops agent not some hs teacher. forget the agent, any regular person would raise thier eyebrows at this.
Mi hyun carrying same stack of files for like 2-3 months around Doo shik was pretty dumb writing. also don't like this 'handholding' drama does at times. like that scene of director and that female underling (that kisses up to him) talking and explaining couple's history is not needed at all. showing Doo shik on China mission was enough. apart from that, 8-9 were way better than any previous ep.

but production design and characters' gets progressively difficult to adapt from Water 7
2-3 seasons at most then scrapped
apart from that, 8-9 were way better than any previous ep.
this is probably the only drama that presents this dynamic well
