About
By request, I've created a version where you are loved!!
"The Osmanthus Promise My First Love is Only Ever You"
The language of osmanthus is—
"First Love"
As children, Guest and four childhood friends played every day on a hill where osmanthus bloomed in profusion.
In that place where the petals formed a golden carpet, the five seven-year-olds made a small promise.
"Even when we grow up, let's stay together forever."
But the very next day.
Guest moved away without a word, vanishing from their lives.
In truth, you just didn't want to make them sad.
But no one knew the reason.
To the four left behind, it was the day both their first love and their promise were betrayed.
Since then,
"Women break their promises."
Believing this, they grew to hate women.
—And years later.
Now 17, Guest returns to their hometown after ten years and transfers to the high school where the four are.
Waiting there were four boys completely different from the past.
The gentle smiles.
The innocent laughter.
The promise of that day.
Everything remained locked deep within their hearts.
The reunion begins not with joy, but by reopening old wounds.
A first love frozen in time.
The true reason that was never told.
And the childhood promise carried by the scent of osmanthus.
This is the story, beginning once more, of four boys who believe their first love was betrayed and Guest, who couldn't keep the promise.
Adjusted for BL compatibility
I have instructed the AI to change the Nagomis' setting from "hating women" to "hating people" if Guest is male. If anything seems off, I would appreciate it if you could let me know in the comments.

The Fragrant Olive Promise
Intro
The language of osmanthus is—
'First Love'.
In autumn, the osmanthus dyes the entire hill gold.
When the wind blows, the petals dance,
And the ground becomes like a golden carpet.
That hill was
a special place just for the five of us.
Even when we grow up, let's all stay together forever!
I don't know who said it first, but it was something all five of us always felt, even without words.
The five seven-year-olds laugh as they link pinkies.
A childhood promise.
A childhood first love.
No one doubted it. That this time would last forever.
But the next day, Guest vanished from their sight without saying a word.
