personally the plot and the actingh was great, but the flow of the story in the first 10 eps is rather slow. from ep 11, we had some twists, which i felt very rushed, to resolve them in the last 9 eps. this also made the backstory of Seong Mo somehow feel incomplete, i'd like to know more about his feelings for Ji Soo, or maybe more about what they've been through. i was also frustrated that Ji Soo died, i was left shocked. and before, i always thought Seong Mo was a good guy, but the plot twist is acceptable as it's not very unexpected.

overall, this is a movie i would watch again, but i consider this as a not verry happy ending for me, cause my favorite character Ji Soo died. but the plot is interesting and it's definitely a great show.
