Everyone knows how the main leads are going to end up together and kdramas always start out with that sort of introduction - however, I LOVE how this drama started out!
Caught me off guard - and how they were able to integrate the plot and piece each of the flashbacks/storyline together.

I cannot be more impressed by EACH and EVERY single cast member chosen for THEIR roles!! Everyone did an AMAZING job; really played out their character to the CORE.

Loved every moment of emotion and feels this drama has put me through... literally cried or got teary every episode.

I loved all the meanings and unique epilogues at the end of each episode (DON'T MISS THEM!). These added great additional information, insight, and plot to the story/characters.

I think the ONLY thing was; as much as unrealistic kdramas are (SNIFF, UNFORTUNATELY T-T) - some violent portions - seemed really unreal but it did play into the plot well...

Some side items - absolutely amazing OSTS/soundtracks; visuals were OFF the charts (outfits, scenery, backgrounds, make up etc etc).

Overall, AMAZING. DEFINITELY worth the watch; no drama is perfect so I give it a 9.9999 out of 10 !
