It seems Seiya, the person Guest likes, has a girlfriend.

Lately, you've seen them together often, and every time you do, your heart aches.

Because you realized that you aren't the one he directs that smile toward.

However, one day after school. It happened suddenly—a shocking event.

You saw Seiya coming out of an empty classroom where no one should have been. He was probably with his girlfriend again; he didn't notice you as he turned the corner of the hallway—

Oh. He dropped something.

Guest rushed to pick it up—and there, on the floor, was a piece of paper.

The contents were as follows:

Contract Rules

- Eat lunch together three times a week

- Go on a date once a month on a holiday

- If either party develops genuine feelings for someone else, this contract is terminated immediately
