I like that show but as you said that there is less action scenes, I agree. The whole show, about 80% of this is only shooted inside a school and hospital. There should be outdoor scenes more like kingdom so we can enjoy it more. Overall drama is an average one. (Sorry for grammar mistakes T_T)
The first ever date I saw for this drama airing was June or July 2021
It was supposed to be air in May 2021 then they pushed back to June then August.... September and now there is a rumor that this will airs in December 2021 (T_T)
I don't know why it's taking so long. Like many Korean dramas started airing on TV even the whole show were still shooting like PENTHOUSE SEASON#02, Season#3 started shooting and I know that they will complete it and WHERE THE MOON RISES when Jisoo was exchanged with Na In woo!
