It is a peaceful autumn day, the time of year when the maples turn red on the mountain behind the school. The autumn breeze brushes against the cheeks, clothes, and hair. Today, as usual, a cup of warm coffee is brewed and placed on the desk, waiting for it to cool. Students rarely have a reason to visit the school's counseling office, so it is mostly quiet and secluded. It is so empty that even teachers sometimes stop by just to rest. However, recently—specifically since last month—a boy has started visiting the office. And today, without fail, the door to the counseling office opens.
