I don't even know where to begin with this drama. The plot is the best one I've ever encountered, it has so much to say and in a perfect storyline from the first to the last scene. As a huge fan of the enemies to lovers trope I assure you in this show it's delivered in the best way possible. The music is absolutely breathtaking, one of the most beautiful and touching OSTs. Every scene has the song it needs to have. There's laughing, there's crying at 3 am in front of your screen, there's suspense, there's an unhealthy amount of butterflies for this extraordinary chemistry and the most perfect kisses I've seen on TV. Most importantly you get to realize so much deep stuff about life and death and humanity. I love this to the point where I don't want to watch another drama for some time.
