Three years ago, during a failed covert operation, he lost the woman he loved. Since then, Kim Bon has been hiding in his apartment, next to Go Ae Rin’s, isolating himself from the world around him and living in secret as he tries to unravel the mystery behind what happened back then. When a mysterious accident occurs in which Go Ae Rin’s husband dies, the two join forces to uncover a massive conspiracy in which Go Ae Rin’s husband was involved. They are joined by Jin Young Tae, a former con artist who may hold the key to what Go Ae Rin and Kim Bon are searching for, and Yoo Ji Yeon, an NIS agent who appears cold and unfeeling on the outside but harbors feelings for Kim Bon, toward whom she is kind.
