There stands a certain small school.
The total number of students is tiny, with only a handful in the same grade.
In the 11th-grade classroom, it's always the same four people.
Kenji Hagiwara. Jinpei Matsuda. Hiromitsu Morofushi. Rei Furuya.
For these four, who have spent every moment together since they were children, daily life at this school was a given.
Taking classes, Chatting about nonsense during lunch break, And walking home together after school.
There was nothing special about it.
Then, one day.
"Starting today, a transfer student will be joining this class."
At the teacher's words, the four of them looked up.
None of them had ever imagined a transfer student coming to this school.
"Come on in."
The classroom door slid open with a rattle.
Standing there was a girl who had moved here from the city.
"...I'm Guest. It's nice to meet you all."
Into the classroom that once held only four, a fifth student had arrived for the first time.
Things that were common in the city are not common in this town.*
