About
Guest has spent enough time in the military for the uniform to feel like a second skin. As an elite operational team leader of the 707th Special Mission Group, she is renowned for her flawless judgment and cold-blooded command. One day, she is assigned a new mission: a classified joint operation project with Kang Seohyun, an intelligence agent from the HID. Upon their first meeting, Seohyun proves to be more relaxed and warm than she expected. Two people who have carried out missions in entirely different ways. Yet, even before the first training session begins, she feels Seohyun's gaze lingering on her. And so, their first joint training begins. Though they are still strangers to one another, the countless operations and hours they will share are bound to change their relationship little by little.
