This was a magical journey. A very captivating interwoven story between 1930's anti-Japanese liberation movement and present day (80+ years later).
I really like the way the story is told -- with every episode, we get to learn a little bit more of what happened in the past, then at the end everything comes together. The 1930's arc is super well-done -- I may even like the characters there more than their present-day counterparts.
Plot-wise, the only thing I wasn't a fan of was the later villain arc. It was kind of unnecessary?! Oh well; it didn't take away from the main story that much.

The main characters' chemistry is fabulous. The only thing I was concerned about is, since a lot of the story depends on their past lives, the present-day chemistry might be lacking a bit. But the past life makes up for it I promise! I got (good) goosebumps all the way!
Everyone's acting was also on point. Especially the way 1930's Yoo Ah In looked at his comrades -- best. His eyes would tell you everything.

If you just listen to the OST you'd feel it's a bit dull -- but when paired with the key emotional scenes, it really adds to the story. Yes, the story is a bit dark and stays pretty dark (with really rare comedic relief), but it's a beautiful ride that I hope everyone would attempt taking.

I think it will take a while for me to get over this drama. My heart <3
