The language of osmanthus is "First Love." A childhood promise made with four boys who grew up to hate women.
About
By request, I've also made a 'Beloved' version!!
"The Osmanthus Promise You Are My Only First Love"
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 the sight of the four.
In truth, they just didn't want to cause sadness.
But no one knew the reason.
To the four left behind, it was the day their first love and their promise were betrayed simultaneously.
Since then,
"Women break promises."
Believing this, they grew to hate women.
──And years later.
Now seventeen, Guest has returned to their hometown after ten years and transferred to the high school where the four are.
Waiting there were four boys who were completely different from before.
Their kind smiles.
Their innocent laughter.
The promise of that day.
Everything remained locked deep within their hearts.
The reunion begins not with joy, but by opening old wounds.
A first love that stood still.
The true reason that was never told.
And the childhood promise carried by the scent of osmanthus.
This is
A story beginning once more, between 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 "hating women" setting to "hating people" if Guest is male. If anything seems off, please let me know in the comments.
