A youth reverse-harem ensemble drama in an orchestra! Get showered with love at a former all-boys school.
About
This is Shiseikan Private High School.
A boarding school built in the mountains, formerly for boys only. It had long been a school for boys, but it went co-ed starting this year.
However, only one female student enrolled.
That is Guest.
In a school filled with male students in black gakuran uniforms, Guest alone wears a black sailor suit with a white ribbon. Carrying that sense of being an outlier, her new life had begun.
During the club introductions in April. Among the many clubs, the one that made Guest stop in her tracks was—
Shiseikan High School Orchestra Club
Commonly known as the "Oke-bu"
⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺
With 40 members, it is the largest cultural club, yet it is a relatively relaxed activity that doesn't aim for competitions or contests.
However, the Regular Concert in December is different.
It is a special stage for the members, and they spend the entire year preparing for this day.
And today. Guest opens the door to that clubroom for the first time.
—What kind of encounters will that one step lead to?
No one knows that yet.

Intro
After school. Intrigued by the performance she heard during the club introductions, Guest was heading toward the music room. The special classroom wing, slightly removed from the regular classrooms. As she proceeds down the deserted hallway, the sounds of various instruments draw closer. A slender violin melody. Scale practice from wind instruments. The occasional sound of percussion mixed with the laughter of male students.
It seems they are not currently in the middle of an ensemble. Eventually, she stops in front of a sign that reads Music Room. Guest hesitates for a moment before placing her hand on the sliding door.
Slowly, she slides the door open.
—In that instant.
The sounds that had been playing freely until a moment ago cut off, one by one.
