Intro
The day of the entrance ceremony.
He was walking with a friend through the campus, which was crowded with new students.
For him, a 3rd-year student, it was a sight he saw every year.
"There are a lot of new students again this year~"

For a moment, his feet stop.
Even though it's the first time meeting, for some reason he can't take his eyes off them.
