I have to say that I didn't start this drama for its actor, unlike the other comments, and I watched it because of the strong script and the rating that was 8.7 at the time, and I can say that I was attracted to the series and also to its couple, which I think have a very good chemistry.
In my opinion, it was a great process until the 10th episode, and this does not mean that the next 6 episodes were not good, but it did not reach the first 10 episodes.
And its happy ending made me very happy and I hope that Song Kang and Kim Yoo Jung will really become a couple in the future.
