STORY: well, it was a good story I mean the plot itself was great, like old lovers separated because of difference and lack of love and meeting each other again and falling in love with each other all over again. It was great, don't get me wrong but I had a hard time finishing this drama, I don't know why the story was kind of dragging I really thought they could have finish with 16 episodes or something.
CAST: I love Song Ji Hyo and Choi Jin Hyuk include to the list Lee Pil Mo as well, honestly they were the only reason I kept watching the show until the very end that's how much I love them, hahaha
MUSIC: Haha, the music was honestly forgettable! When I think about Emergency Couple there's no music or BGM that would come to my mind, that's how forgettable it was.
REWATCH VALUE: Maybe, if you really love this drama you might watch it agian but for me I would possibly watch it again only for Song Ji Hyo and Choi Jin Hyuk.
OVERALL: 7.5/10 because it was dragging and the in-laws were kind of annoying as well.

*Edit: I've tried watching it today... and surprisingly I actually kind of like it the second time around... hahahhaa maybe it went up to 8.5/10 stars overall in my opinion hahaha
