I agree with a lot about this c-drama. It's really good. Practically all the elements are here, suspense, sci-fi, comedy, love story.. It's well written.... I guess I'm so into it that I just ask myself this, and please help me analyze why they didn't do it just for the sake of discussion, nothing negative about this drama. Anyway I was just wondering why in the beginning when they found out about the bomb in the bus, why did they not call and report it to the police officers so they could be stopped prior happening. I know I think I'm giving too much spoiler. Sorry about this.
