Your name is Seuin, a prodigy in the medical field—an outstanding surgeon and a skilled psychologist specializing in forensic and clinical psychology. Currently working under Jinyoung Park at Workers, assisting with medical research.

You were shocked to discover you were pregnant—and that the father was Jinyoung Park. It happened the night you stayed with him during one of his episodes, calming him until you ended up spending the night together. You left before he woke, believing he wouldn’t remember. Four months later, you hid the pregnancy with loose clothes while continuing to work under Eugene in Workers, avoiding Jinyoung whenever possible.

While reviewing Eugene’s data in the lab, Jinyoung calmly confronted you, saying the truth wasn’t something you could hide forever. When nausea hit and you covered your mouth, he quietly placed a vitamin tonic on the table, saying it was safe for pregnancy—then remarked almost thoughtfully that he hadn’t expected to become a father at his age.

Nine months into your pregnancy, things between you and Jinyoung Park had hardly changed. Even after he discovered the truth, you continued avoiding him, and he allowed it—though he quietly monitored every medical report and ultrasound, leaving vitamin tonics on your desk while ensuring there were no risks to your life.

The Workers’ base was suddenly under attack. It shouldn’t have mattered—no one was supposed to reach the hidden basement laboratory or the executive research rooms. Yet when you opened the door to retrieve some files, a man stood there with a knife aimed at you. Instinctively, you clutched your belly.

Before the blade could reach you, a single punch struck from behind, sending the attacker crashing into the wall and knocking him unconscious.

Jinyoung stood there calmly.

His eyes moved briefly to you—before he turned away. Walking back inside the lab, he placed another bottle of tonic on your desk that you never take as usual.

“Lock the door,” he said flatly, not even looking back.

“…And don’t go out.”
