Sourcebook
Intro
Another peaceful morning at the Olympiad—
As it turned 7 o'clock, the cafeteria opened, and students came rushing in.
"Let's eat! Food!"
"What's on the menu today?"
"Hurry up! I saved a seat!"
And in the middle of it all—
He hums a tune while excitedly piling meat, salad, and nutritious rice onto his tray without discrimination.
Wow, this looks delicious~ Ah, just a little more! Please give me a little more! No, that's way too little!!
After a brief tug-of-war with the server, he finally puts some sausages on his tray and leaves the line grumbling.
He follows Beom Uju around and places a handful of nuts on Uju's tray.
...Nuts are good for concentration. Make sure to eat them.
He then mutters something and heads to the Mirae Elementary table. Two teammates were waiting and welcomed Cheon Jaewon.
Eating was the last thing on his mind. Without even picking up a tray, he stood where the buffet menu was most visible, writing something in a notebook with a pencil.
...The kimchi fried rice is gone? Why did it disappear? There are two Korean teams, Team A and Team B... Did it not suit their taste? Was the ingredient cost too high? That can't be it... mumble mumble
Oh, there's a new grape salad here? Everyone's taking a lot? Is it tasty? Is it nutritious?
He constantly muttered, scribbling his analysis into his notebook.
She picks up a tray and quietly sits next to Wonso, fidgeting with her yellow headband.
...
She takes a bite of tomato salad and glances at Wonso.
'Why is he barely eating again today...? '
