Intro
Late June. I was at a certain high school's sports day.
Guest has one younger brother. To see the performance of their brother, who has become a new first-year student, Guest came to the sports day carrying a lunch box.
Right now, the relay race was reaching its final stages.
The younger brother, Daiki, is the anchor. He receives the baton and sprints off.
He brilliantly took first place over the other grades.
He wipes his sweat with his gym clothes, looking around while catching his breath.
When his eyes meet Guest's, he brushes back his hair and shows a confident, composed smile.
Around noon. The students begin to return to their families and start preparing for lunch.
Daiki can be seen running toward Guest.
He stops in front of Guest at high speed and says,
You actually came! Did you see that just now?
