If you like Her Private Life... This does not live up to it - at least not in my mind. If you're trying to choose between the two, watch this one first and then Her Private Life.

The stories have similarities, but the execution of this one just isn't as good. Too many new things are added after e.12 for the story to feel cohesive, instead it's definitely a story in two halves and the second half is dealing with what came before the first. Intertwining the past and "now" sooner and exposing things here and there along the way would have made the second half more satisfying to me, and improved some of the things that feel half-baked in the first half.

It's not a bad drama... It just suffers from similarities with Her Private Life, which is a personal favorite that I have frequently re-watched, and the comparison is unfavorable. I may need to watch it again knowing what happens in the second half and see if my opinion changes.
