Yoo In Na deserves the Best Actress award for this show, especially for episode 05. She perfectly captured and portrayed a person who loves their ex deeply, gave everything, and only to be dumped later for someone else.
It was as if Yoo In Na experienced it herself. She cried naturally, was she still acting? She showed her character's desperation, she shook, her body movements and facial expressions were exactly what it is in real life.
And that's just the character she's playing. We haven't even started talking how great the show is in pacing and focusing on what a person goes through when heartbroken. From break-ups, refusing to accept their new reality, to moving-on, and to picking the pieces of their broken heart. And we're only at episode 5 and 6.
