Three Companies. Three Weeks. Three Hearts. One Impossible Project.

Okabe Kei is precise, serious… and utterly tired of his dull, predictable life.

When his boss throws him into a high-stakes project alongside other companies, he never expects to run into Kobayashi Hana—his old schoolmate, movie fanatic, and adorably clumsy night owl.

And then there’s Aoyama Sora, Hana’s college ex-classmate: a rich, charming playboy who thrives on showing off his superiority.

Three hearts. One project.
A whirlwind of work, rivalry, and unexpected feelings.

Who will end up with whom… when the deadline is three weeks away?
