I made sure not to watch sad ending for some personal reasons.. It didn't come to me that this will have such ending. But I manage to pull myself together and watch it thru - that's how good it was! I am hooked that it was an action film and the lead actor really looks hot! Though there are unanswered things like how did the female lead get in the orphanage when she was young and she has a name, also I don't know if English translation was not precise but I read somewhere where Suel Gi's biological father is Soo Hyeon? What??!! But over all it was a good watch! Of course all because of Jang Ki-yong and the female lead was also very good! They are well blended together even if there are no lovey dovey moments!
