this was just hilarious, action packed and good. i dint like kim ha neul in a gentlemans dignity but this changed my mind. she was so good and i enjoyed every minute. the nerdy boyfriend always looks present even in the drama lie to me. the two were so interesting to watch. so she is an undercover agent and has a needy boyfriend who wants nothing but love and time from her but shes always caught up in her job. he caught her in a lie but she still found a way to get out of it. finally he leaves and dumps her then comes back three years later as a rookie agent and wants her back. they both keep it a secret from each other but find themselves working a similar case. its the korean version of mr and mrs smith except brad is not a nerd.
