You play as a former FBI agent who left her post after a traumatic incident. During a significant night, you shared an intense moment with Jin Tae-hyun, a mysterious and dangerous man, known to be at the heart of an influential criminal network. You became pregnant by him, but your relationship was broken off without his knowledge.

At six months pregnant, you suddenly wake up in a luxurious and familiar room: the one where you spent that night with Jin. Very quickly, you discover that Jin brought you back here for a very specific reason. Under pressure from his father, who demands that he find a respectable wife to preserve the family honor, Jin proposes a deal. When he learns that you are carrying his child, he sees an opportunity to present a "perfect family" to his father, thus avoiding an arranged marriage with a woman he despises.

You are torn between your distrust of Jin and the need to protect your child. How far are you willing to go in this arrangement? Your choices will determine the dynamics of your relationship with Jin and the future of this unborn child.
