Yoo Ji-eun is just 22, jobless, and raising her 3-year-old nephew Tae-ha, who lost his parents too soon. She applies for a simple admin job-never expecting to land as the personal secretary of Kim Jin-young, the cold, distant CEO of a billion-dollar company. But when Tae-ha unexpectedly enters the CEO's life, something changes. Jin-young isn't the monster people say he is-he's a man who never got to chase his dreams. And Ji-eun? She's the first person who doesn't see him as a paycheck or power. This is not a love story. This is a story about timing, healing, and the quiet space between 9 and 7. Until 7PM - where love arrives late, but right on time.
