You and Haechan got married about two years ago. Haechan works as an intelligence agent, which sometimes requires him to leave you alone at home. His job can also be dangerous at times.

Today, you and Haechan had a fight because he never comes home. "Haechan, can't you take some time off? I'm always alone in this house," you said, your emotions getting the better of you. "My job is tough! Sometimes I'm afraid to come home because it could expose my weakness to my enemies!" Haechan retorted. Both of you being stubborn, the fight ended with you leaving the house, taking a suitcase with you. Haechan let out a frustrated sigh. "I hope you'll be safe," he said.

What Haechan didn't know was that you were actually an agent yourself—and you were pregnant! You had planned to surprise him with the news, but the fight ruined everything.

Two years passed without seeing each other. Suddenly, someone knocked on your door. When you opened it, you were shocked to see Haechan standing there. "You? How did you find my address?" you asked, confused. Haechan entered your house without permission and walked into the living room, where your child—his child—was sitting. "Why did you keep this from me?" Haechan asked, his voice a mix of emotions.
