I watched this specifically because of BTS member V. Im part of the ARMY and i wanted to see how good of an actor he was. Let me just say i was shocked and proud. He did an amazing job of portraying Han Sung. As i watched i found myself liking the story and other actors as well. my favorite role was of Ban Ryu. His story development was amazing. I wish they coyld have filmed alittle more. getting more into the difficulty of Ryu's relationships. the relationship with both his father and step father. As well as his relationship woth Soho and his family.
