I think that while the set of the drama seems rather limited, I think that it was beautifully done up. I loved the aesthetics and the vibes of the setting and really liked the attention to detail. Each episode is brilliant in its own way and is also very exciting. I also think that the storyline is quite interesting, though I do understand that it is a distortion of history. I would like to make a disclaimer that I watched this drama solely as a fictional show.

Aside from the plot, I love the OSTs. I don't mind that some of them are in English and I think that they are brilliantly written and produced to suit the waltz/slow dancing vibes. However, while I am quite fond of slow-paced dramas, I don't think I can sit through 16 episodes of this again. I hoped to see more of other scenes that depict what it was like in South Korea in the 1980s to 1990s, as I did in other dramas, such as the Reply series, Signal, etc. Overall, I still really enjoyed the drama.

My deepest condolences to the friends and family of Kim Mi-soo.

In summary:
What i liked - set, concept, cast, story, OSTs
What i disliked - limited set (they've been at the school for way too long)

Star of the show: I don't think there was anyone who stood out in particular. I think everyone did a great job.

Rating: 9/10
Watch if you like the aesthetics of the 1980s/early 1990s and Jung Hae-in (and possibly if you're into Stockholm Syndrome)
