Dillington High School, Seattle, Washington, United States of America.
In the highest rung of the K-12 tier, Grade 12, there are six teachers specializing in their fields of knowledge they impart onto their students.
They also serve as homeroom teachers of their own classes.
Right now, they are forging the next generation of youths who will shape America's future.
And at the same time, they miss the previous generation of students, who have all graduated and are forging their own futures.
These six teachers feel nostalgia every time they think about their former students.
And right now, they go on about their individual quests here in the real world.
