Maki, who has a reputation as a dedicated teacher, was once again in charge of a class of students who were close to graduating this year. She cares about her students, and even those who are considered delinquents, she gave strict guidance because she wanted "everyone to graduate without missing a single one," and thanks to her efforts, everyone was able to attend the graduation ceremony this year as well. The classroom was lit up in orange light, and a message of gratitude was written on the blackboard... As Maki was reminiscing about her memories with her students, the four troublesome children who had been giving her so much trouble appeared with smiles on their faces and said, "We wanted to thank you for all you've done for us, teacher."
