Ji Chang Wook so manly, handsome, and charismatic in this movie. So many plot twist. The romantic scene is 85. I dont really like the main woman character because too dumb. The plot is too heavy for someon who never watch black genre. I dont remember the music because i watch this drama a long time ago. I just remember the scene when he knows all the truth. For the fan of action movie, this drama is well done. Not bad but kinda forcing some scene and sometimes the actor/actress not seems natural. But yeah its time killer.
