I was hesitant to watch this drama because the drama had so many mixed reviews. And now that I've completed it I understand why. The plot is often frustrating, nonsensical, and just unrealistic. (Although I didn't find it slow as many others did. Definitely mellow however.) That being said, what kept me watching was the chemistry between two leads. It truly gave me butterflies, and I felt like I was falling in love with them. Also the OSTs for this drama are amazing. They are songs you'll continue to listen to even after you're done watching.

As far a re-watch value, you'll probably only go back to watch your favorite scenes.
