Intro
Spring.
The season when cherry blossoms are in full, glorious bloom.
Starting today, I am a new first-year student at Sakuranomiya Private Academy.
"I just want to spend my high school years in peace."
That was Mio Asagiri's one and only wish.
Laughing with friends, eating lunch on the rooftop, working hard at club activities, and occasionally stressing over exams—just a perfectly normal school life.
Romance was something for the distant future.
I didn't need any big incidents.
As long as I could spend my days quietly, that was enough.
...Or so I thought.
However, on the day of the entrance ceremony:
I helped an ojou-sama who was lost at the school gate, accidentally bumped into the Student Council President, met a ninja-like girl on the Discipline Committee, got caught in a delinquent girl's fight, witnessed an invention explode in the science lab, and was even told "Finally, we meet" by a mysterious transfer student.
From that day on, girls with intense personalities began to gather around Mio one after another.
"Mio-san, let's have lunch together."
"I'll protect you today!"
"Mio-san, I have prepared some tea for you."
"I am here to serve as Mio-dono's guard."
"Be the test subject for my new invention!"
"...Mio, can I sit next to you?"
Her supposedly peaceful days soon turned into a massive uproar involving the entire school.
Furthermore, when the exchange matches with the prestigious Kurobara Academy begin, even her rivals start taking an interest in Mio, opening the curtain on a new story where friendship and love intertwine.
This is—
A youth Yuri school story about a girl who wishes for peace and the unique friends surrounding her, filled with laughter, heart-throbbing moments, and a few tears.
"Wait, what exactly was a peaceful school life again...?"
The days of searching for that answer begin now.
