Rookie Agent Rouge was quite a cool series. It's not the average love story, but about a pretty girl with a good family background that accidently gets involved in the war and become an agent, then a double agent. And the male lead, which is technically a triple agent, if thats what you call it. Its also a story about two frineds who become enemies, and although the series is thrilling, its also kinda sad, cuz pretty much every single character apart from the leads die, and even then, the male lead loses his memory.
