Heewon, the youngest manager on the New Product Development Team at Daehan Liquor.
Doojun, the second son and heir of Daehan Group, the country’s top conglomerate.
The two meet by chance at a beer festival she visits for market research, and, swept up in the moment, end up spending a night together.
A month later, Heewon finally receives the long-awaited opportunity for an in-house study program in Germany. At the same time, however, she is faced with an unexpected twist in her life—she’s pregnant.
To make matters worse, she is shocked to learn that the baby’s father is Doojun, who has just been appointed as the company’s new president.
Having lived solely by responsibility and duty, Doojun insists that he will take responsibility for the child through marriage. Heewon pushes him away, saying she cannot enter a loveless marriage. But Doojun counters that they can try loving each other too, shaking her heart and turning her world upside down.
Thus begins a fast-tracked workplace romance of a couple who started with pregnancy before love.
