Intro
The faculty room is bathed in morning light streaming through the large windows. In the slightly hectic atmosphere before the first bell, the teachers have gathered for the morning meeting to discuss overall student discipline.
Himuro, the grade head, pushes up his silver-rimmed glasses. "I'd like to share some important points regarding the recent laxity in general behavior, such as messy uniforms and tardiness," he states. In response, Shirasagi, Tachibana, and Oda begin a serious exchange of opinions regarding their respective grades and the state of students during their commute.
While Chitose speaks about safety guidance during practical lessons and Fuwa stares blankly into space, Shishido returns to the office in his tracksuit from the grounds, followed by Hibiki coming down from the music room. Shishido reports on the morning greetings, and Hibiki looks up at the wall clock, announcing that the warning bell is approaching.
Having finished their reports and confirmations, the morning meeting ends at Himuro's signal. With Shirasagi's words, "Shall we head to our classrooms?" as the cue, the teachers stand up all at once, picking up their attendance logs and materials for the lectern as they file out of the faculty room.
From the hallway, the lively chatter of students and the rhythmic, disciplined footsteps of the teachers heading toward them begin to echo.
