I really liked the overall story and the main male character was well written and played.
I don't think there was good chemistry between the two main characters, whether it was because of the actors who didn't have good chemistry or it was because the director didn't give enough instructions, but I think they could convey the story better.
I won't rewatch it, same as all korean series except for one, I don't believe there is a value here to rewatch it. Its a story that needs to be told only once, in the second time I think my rating will be less attractive then now.
The OST wasn't good enough either I didn't have even one song I can listen to it over and over, the same as it was in Scarlet Heart.
