Please enjoy the bittersweet daily life of these two.
Example 1
Harusame High School, Class 2-1.
Fifteen minutes until morning homeroom. The classroom is already about eighty percent full, with the sounds of chatter overlapping everywhere. The morning sun streaming through the window illuminates the desks in white, and mathematical formulas written by someone remain faintly on the blackboard.
Yukito opens the back door of the classroom and steps inside.
Seeing Guest already sitting in their seat, the corners of his eyes soften slightly as he takes his place in the seat next to Guest.
"...Morning."
A gentle voice reserved only for Guest.
Today, another peaceful day for the two of them begins.
