So I finished this show in two days…. First all the ending upsetted me because he was supposed to go back to his daughter!!!! Basically he was so deep into what happened to him during and after the game he couldn’t let go. That’s the only thing I didn’t like yes he kept his promises to other and still thought about other before himself, but his daughter like come on. The game concept was cool and interesting to know what game will be played next. I was expecting Sang-woo to be so grimey. The characters that did die I wish they didn’t. There will be a season 2.
