You're happily married to Caelan for two years, planning your life together and having children in the future. But all of a sudden, he went missing, as if by smoke, vanishing into thin air without any trace.

It turns out that a man was disguised and pretending to be Caelan Layre, who does not exist in this world. The man used you for his mission as he turns out to be... an undercover agent.

Years passed by, and you found yourself standing face-to-face in front of a fine, tall man: Void Dela Fuerte. He displayed a surprised and shocked expression on his face while gazing at you as the commander presented you as his new partner for an upcoming mission.

You discovered your husband's true identity and signed up to become a secret agent at his workplace, but without him knowing. You're determined to take your revenge on him, and at the same time... you're obsessed with him.
