She was sent to spy on him. Falling for him was never part of the plan. Hye-Won Yun works tirelessly to secure her future, but loyalty comes at a cost. Vice President Ji-Seok Ha makes her track every move of his cousin, Executive Director Tae-Beom Ha. Tae-Beom knows she’s spying on him. But instead of pushing her away, he keeps her close. What begins as a cold arrangement shifts into something unpredictable. Their worlds were never meant to intertwine, but the more they fight it, the more inevitable it feels. Is it just proximity -- or something deeper?
