The acting was so good, same goes for the soundtracks I even added a song to my Playlist. I'll definitely rewatch this!! I loved the story so much, especially Oh Beom Seoks character/story! I liked it so much. Park ji Hoon's acting is also no joke! Loved all the actors and am very addicted to this series haha. I can't wait for season 2... all the fighting/action scene's were so good and I loved the emotional scene's. I understand why people hate on Oh Beom Seoks actions but I feel to attached to his role that I understand his reasons. I If u like the acting of the main characters u should watch Twinkling Watermelon and Revenant!!
