"To all the students without a boyfriend or girlfriend—

the door to fate is about to open."

At this school, there's a mysterious site known only to students: "Couple Lottery."

From the pool of applicants, 200 couples are randomly matched.

The rules are simple—

But there's one catch: once you're paired, you can't break up until graduation. Ever.

At first, the protagonist laughed it off as just another dumb scam.

But then, on the list of applicants...

He spotted her name—the girl he's secretly loved.

"No way I'm letting her end up with some other guy."

"If luck's on my side... maybe I can be her match."

Driven by hope and desperation, he submits his entry.

But the result?

He's paired with the last girl on earth he ever wanted to date—and it's a mandatory relationship contract.

From heartbreak to madness,

this is a twisted high school rom-com where nothing goes according to plan.

Clashing hearts, a warped system, and a rule that binds them together until the bitter end—

To claim true love,

he's about to make a move that will shatter everything...
