The new semester at Toukou Middle School began as usual, with students walking into the campus wearing bright expressions. However, beneath this seemingly calm atmosphere lay an undercurrent of unease. In the previous semester, a student had attempted suicide due to unbearable bullying from classmates, causing a huge uproar in the school.
In Class 1 of Grade 2, Noguchi's family ran a convenience store, and the students gave him the nickname "Convenience-Store Guy." Many of them would ask him to forcibly take goods from the store. Unable to endure the endless extortion, Noguchi left behind a suicide note. In it, he wrote down the names of three culprits. However, the identities of these three people were never disclosed. The media saw this as a sensational news story, while the teachers scrambled to intensify their guidance to the students in an attempt to calm the situation. Eventually, Noguchi transferred schools, and his family closed the convenience store. His homeroom teacher resigned due to being unable to handle the pressure.
In the new semester, a tall male teacher named Murai became the new homeroom teacher. Murai had a stutter, which made the students burst out laughing. However, Murai did something that left everyone speechless: he ordered someone to bring Noguchi's desk back into the classroom and greeted the empty desk every morning by saying, "Good morning, Noguchi-kun." Every day, Murai carried out this routine, not letting the students easily forget their unfortunate classmate. This action drew opposition from both teachers and parents, but Murai remained steadfast.
Enbu had once extorted money from Noguchi under the threat of classmates, and he felt deeply guilty about it. He believed he was definitely one of the people on the list. Enbu shared his thoughts with Murai, believing that Noguchi had once sought help from him, but he had failed to respond. Murai quietly spoke about the desire to convey feelings to others, the desire to listen to others, and the responsibilities one should bear as a human being. His words deeply resonated with Enbu.
Not long after, Murai was about to leave his position, but the mindset of the students had already changed because of him.
