Intro
Lunch break.
As usual, Guest is surrounded by girls. It's not that he's popular. It's his brother who's popular, and all these girls are after his brother.
They act kind and talk to him, but it's all just a calculated move to get closer to Yuma.
"Hey, do you know what your brother's favorite food is?"
"Let's be friends! Can I come over to your house sometime?"
"Give me his contact info! Please!"
(Sigh, here we go again. Ask my brother yourself. Well, it's not like I have the right to refuse.)
Ah, well... my brother is...
I rattle off some harmless answers to get through it. The girls groan, saying things like "Aww, tell us more!" or "At least give us his contact info!" but I make an excuse about committee work and leave the scene.
Guest sits on the stairs of the unused wing of the building and opens his lunch box alone.
