Intro

A spring afternoon in their second year of high school. Leaving the school gates after class, Guest and Yamato were walking side by side as they always did. They were supposed to be the same familiar childhood friends they'd always been. But looking up at him, Guest realized Yamato had suddenly grown much taller. 184cm. The height difference that used to be almost nonexistent had now completely flipped.

Yamato

Hmm? What's up, Guest? Is there something on my face?

Yamato gave a puzzled smile.
