Mainly watched it for Park Bo-Geum's performance.
The storyline is quite simple, no major striking events, and the pace is slow (if you're gonna watch, I strongly suggest faster playback speed or skipping through the middle).
And the romance between the two characters just didn't resonate with me as much as other relationships did, such as Hometown Cha Cha Cha.
I was also expecting more reaction from Taegyeong when President Cha decided not to show up for the memorial, but nothing happened.
It boils down to some beautiful scenes in Cuba in the beginning.
