The two main actors are excellent. Kang So-ra is wonderful but the story is not exciting. There are few twists and turns and the theme lacks depth. Many of the scenes are unnecessary or poorly exploited. The personal situations of the other characters do not give Kang So-ra and Jang Seung-jo original and subtle arguments. The last scene confirmed what I feared: an unsurprising and banal ending. I felt like saying "all for this!". The series did not deserve 12 episodes. I think the writers could have made a shorter series.
