story- with such limited minutes and episodes , this series managed to develop the plot to such lengths

acting/cast- i can say the acting is commendable considering that the story required a variety of emotions. you can really see in their eyes what they are feeling and their chemistry is phenomenal, it's burning. for the cast, i was really surprised that they have a 9 year age gap, they look like of the same age making the casting great.
*edit - while reading other reviews i agree that the acting of tae joo with his father was kind of cringey

music- considering this drama is short in terms of hours, it contained a lot of ost which is effort. and the songs are actually good as well.

rewatch value- becuase this drama is not that long and the plot progress really fast i think you will not be bored if you are gonna decide to watch it again
