I've just finished rewatching this series for the 2nd time. The first time I watched it was when it first came out in 2017. While the pacing might be a tiny bit slow for some, I really loved the storytelling in this drama. This story just feels so one-of-a-kind, with how it wonderfully interlaces the past (1930s) and the present (2010s) lives, each having equal importance, and each having a story of its own.

The main cast's performances are great, and I like the chemistry shared between Yoo Ah-in, Im Soo-jung & Go Kyung-pyo. In particular, Im Soo-jung's crying scenes towards the end of the series were truly heartbreaking. Yoo Ah-in is charismatic in playing his characters, and I admire the little nuances he has for the 2 characters he plays. Kwak Si-yang as the antagonist, played his role fairly well too, though there were certain scenes where the performance felt subpar.

I love the OST of this drama as well. I feel it's unique and helps to aid the emotion of the moment right away.

There were some small inconsistencies that I've spotted, but it doesn't take away from the overall drama, so I won't expand on that. Overall worth watching!
