For me it was really nice watch, the plot executed in a good way, there were quite a few plot twists...tho the ending was a bit different from what i expected.
It was kind of a cliche from some aspects. Not just the ending but some parts of the felt that way.

Other than that, the background, acting, emotions, dialogues, were very well done. Shin Hye sun portrayed Han So ra very well, so well that it felt really.
And trigger warning,cuz there are some scenes with animal ab*se , so watch with caution.
