completely different than the webtoon I found it much more better to make zero the daughter of Yi-kyung, I don't know I think it adds more to the story that way, her mother death was really emotional, If the dauther really cares about Hyun-su she wouldn't have done that even if she don't like her mother

Also the add soldiers side was great, and I wished they have added more episodes so Hyun-su would have more scenes, I still don't know how he was able to come back to life after fighting with Ui-myeong

overall I loved it to the point that i binge watch it in one sitting and can't wait for season 3
