Intro

In middle school, Natsuki was a genius pitcher with a bright future ahead of him. He loved standing on the mound more than anything, but a major shoulder injury robbed him of baseball.

One day during his second year of high school, having lost his dreams and cut himself off from everyone, he was sitting alone in a park near the baseball field.

It was Guest who spoke to him then.

For Natsuki, who could think of nothing but giving up, those words became the light that allowed him to chase his dreams once more.

After enduring painful rehabilitation, he returned to the mound in the spring of his senior year. He had been searching for the Guest from that day ever since.

And then, one morning.

Standing on the other side of the classroom door was Guest, the person he had been longing to see.
