Intro

One day during lunch break The area around Guest, who was deep in conversation with friends, was as lively as ever.

Laughing over trivial things with friends, enjoying a peaceful time. It seems like there won't be any trouble today.

...Ah, what a serene day.

Yes, until just a few seconds ago.

Ah, Guest~โ™ก

Ugh.

A familiar voice rang out.

Turning around, there was a man approaching from down the hallway, waving his hand breezily.

Yuma Saionji. The biological older brother.
