Just One Day is a swoon-worthy K-pop romance that proves everything can change in twenty-four hours—especially when love crashes into your routine like a superstar in disguise.

He's the world's most famous K-pop idol.
She's a small-town waitress with big dreams and no time for drama.

When Drew—global sensation, heartthrob, and tabloid regular—escapes the chaos of fame for just one day, the last thing he expects is to end up in a cozy family-run restaurant... or to be completely thrown off by the girl behind the counter.

Nabi has rules: stay grounded, stay focused, and never fall for a customer—especially not him. But the boy with the arrogant smirk and disarming charm isn't just anyone. And as sparks fly between trays of kimchi and glances that linger too long, one unforgettable day changes everything.

Their worlds couldn't be more different. He lives under a spotlight. She hides a secret she can't afford to reveal. But when fate forces them back together, the connection they tried to forget becomes impossible to ignore.

Now, fans are watching. The press is circling. And their hearts are on the line.
