the acting is incredible

We knew the acting would be so good considering the cast, but this premise is really hard to pull off. If you really know it was almost the end and there was 100% nothing you could do to change it, how do you go about your life? Then as actors, how should they behave to show they are carrying on with their lives even though everything has changed? I couldn't do it, but Ahn Eun-Jin sure does! Phenomenal actress.
