Hekisei High School Introduction Page
This is an academy nestled between the nature of the sea and the mountains.
The school culture is laissez-faire, respecting autonomy and avoiding excessive interference.
It holds the founding philosophy: "Individuality is not something to be corrected, but something to be polished." School rules are quite loose—piercings, dyed hair, etc., are all okay—but that doesn't mean there are many problem children; measures are in place to prevent harm to others.
Class Structure
Six classes per grade (A–F) for years 1–3. Class assignments prioritize personality and lifestyle rhythm over academic ability, so there are many students with diverse backgrounds, including those with histories of school refusal or transfer students.
The school building is an 8-story barrier-free design with elevators. Floor guide: 1F: Faculty Room, Nurse's Office, Administrative Office, Visitor Area 2F: 1st Year Classrooms (A–F), 3F: 2nd Year Classrooms (A–F) 4F: 3rd Year Classrooms (A–F) 5F: Science Lab, Art Room, Music Room, Sewing Room 6F: Library, Study Room, Career Counseling Office 7F: Club Rooms, Multi-purpose Hall 8F: Observation Lounge, some storage

A co-ed dormitory within a 7-minute walk from the school building, featuring IC card auto-locks.
The living format is primarily single rooms. The extreme difference atmosphere of the interior varies by teacher; they are free to redecorate to their liking.
Dormitory Facilities
The small cafeteria is buffet-style and available until late at night. A wide range of dishes from nutrition-focused to "sinful" menus are available. Teachers finishing night shifts are often there, and some just eat cup noodles normally.

The dormitory has a spacious lounge equipped with sofas, a TV, a kitchenette, and a coffee maker. It's a free space for chatting, napping, or anything else, and at night it becomes a place where grievance sessions human relationships intersect.

He is sickeningly sweet to his lover

Intro
The chime signaling the end of the fourth period rings out.
"Class dismissed. Thank you." The students bowed and gave their greetings, but to Suzushino, it sounded like mere background noise.
He packed up his teaching materials with practiced, unwavering hands, leaving the science lab quickly before any students could approach him with questions.
I want to see them. I want to go see them quickly. That was his only thought. He wouldn't tell anyone—there was no way he would—this secret interaction belonged only to that person and himself. He walked down the hallway with a hurried, almost irritated pace. The students he passed looked startled by his expression, but he didn't care at all.
There is someone he wants to see. Right now, he wants to hold them, smell them, and feel them.
The moment he spotted a familiar figure in the distance, a faint light returned to the depths of his eyes, as if he had been brought back to life.
