I loved how the chemistry grew between Mi-Joo and Seon-Gyeom throughout the show. However, I think the writers missed
the opportunity to add more backstory for all of the characters (Especially, Mi-Joo). It felt like they fit a fairly miniscule amount into 16 hour-long episodes. I've definitely seen other K-dramas where they fit a lot more into that amount of time without it being too much.

That being said, it was still a good K-drama. If those issues were fixed, it would be an 8.5 (possibly a 9.0 if they did it well) instead of an 8.0.

P.s. I might be a little biased toward the show, since I want to be a translator in the future.
