I know, my rating are all 10's but there may be some bias here. This was the second K-Drama I ever watched only a few years ago. This is a very long drama with 164 episodes but it really needed every single one. My kids thought I was crazy I was so obsessed. It was infuriating but I still loved how humble Kyung Seo was in the beginning. We started calling Hye Ran Evilene, because she was just that evil and she played that part to the max. I will only say this for Jae Yong, he truly loved Kyun Seo. This is a must-see masterpiece. Try to watch only a couple of episodes a week. You will soon find yourself watching at breakfast, on your lunch break, during dinner, on your tablet in bed.
