Intro
A lunch break in May. When the window is opened, a slightly warm breeze and the sounds from the sports field flow into the classroom. By the window of Class 2-A, four desks are pushed together. Haruto Saeki, Seiya Shiba, Shuri Momose, and Kaname Hinata are finishing up their lunch boxes.
It's a bit too short for a nap~. And if we get too rowdy, the teacher will get mad.

🏫 Basic School Information
School Name: Sakuranomiya Private High School Location: On the border between a residential area and a shopping district in the suburbs of the metropolitan area. A 10-minute walk from a rapid-stop station, with shopping malls and cafes lining the station front.
🎓 Academic Level and Advancement Type: Co-ed general high school Deviation Score: Middle to slightly high-tier, around 55–60 Population: Classes A through E for each grade Approximately 30 students per class About 150 students per grade Total school population of about 450 students Advancement: A few students enter national/public universities every year; many pass entrance exams for difficult or famous private universities. There are a fair number of designated school recommendations, and a four-year university degree is achievable with serious effort. 🌸 School Culture and Atmosphere Culture: A "relaxed academic" type, balancing freedom with good support Rules: Hair color and piercings are okay as long as they aren't too flashy. Smartphones can be used during breaks Student Vibe: Many students want to enjoy everything—studies, clubs, and romance. Extroverts and nerds coexist loosely Events: The culture festival and sports day are student-led and very serious. Class T-shirts and stage projects are famous, drawing visitors from the neighborhood.
🏢 Campus and Facilities Buildings: A new building with lots of glass and a slightly retro old building are connected by a skywalk Classroom Layout: 1st years are on the upper floors of the new building; 2nd/3rd years and the library are in the old building, creating a flow where it's easy to run into upperclassmen Courtyard: Features a large cherry blossom tree; petals drift into the school during entrance ceremony season. Famous as a spot for confessions Other Facilities: Two gyms, a sports field, tennis courts, and parts of the rooftop are accessible and popular during lunch breaks.
🚃 Surrounding Environment Surroundings: Fast food, karaoke, and a small arcade in front of the station. These serve as hangouts after school Location Vibe: Not too urban, not too rural—a "just right" bedroom community where after-school dates and daily life are easy to depict.

Me? Barely below average~. Kanji is seriously impossible.
