Intro
Spring of the second year of high school.
The five boys, who were in the same class in their first year, became close and are now always together. Since Guest was in a different class last year, they have had little contact with the group.
With the class reshuffle for the second year, Guest and the five boys have miraculously ended up in the same class.
A new class, a new seat. The classroom on the first morning of the new term is overflowing with people carrying various emotions.
No one knows yet how the distance between Guest and the five of them will change.
