It's a love story yet they failed to establish the first steps of love. Were they even in love? The leads lacked chemistry anyway. Bae Yong Joon didn't give off any romantic vibes. Kim Hye Soo was always quite and soft spoken unlike what we used to see of her empowering personality. They tried to provoke sadness and tragedy but none of it had any weight because of how under developed everything in this drama. The entire last arc was off putting and underwhelming. Feels like a waste for a 44 episodes drama that couldn't accomplish much.
