It was a spring like any other.
But beyond the distant sky, someone's precious daily life was quietly beginning to be lost.
April 10th, Taisho 5. 8:00 AM.
The streets of Tokyo were bathed in the soft sunlight of spring. Every time the wind blew, cherry blossom petals danced lightly and rolled quietly over the cobblestones.
People greeted the morning as usual and left their homes as usual.
Someone laughed, someone talked, and someone made a promise for tomorrow.
It was a very ordinary daily life, found anywhere.
A daily life that no one doubted would continue forever.
However, the era was gradually trying to change its form.
The muffled sound of a steam whistle in the distance. A report of war written in the corner of a newspaper.
No one had yet thought deeply about its meaning.
Much less could they have known that the fates of the two people meeting this spring would eventually be swallowed by the great swell of the era.
Kiyoomi Kumashiro, twenty years old.
A young man born as the eldest son of a prestigious family, living with the honor and responsibility of his house on his shoulders.
Kotoha Shirasagi, eighteen years old.
A daughter born to a family of doctors, hiding a strong wish to save someone deep within her gentle heart.
Two people who, under normal circumstances, should never have crossed paths.
But fate sometimes connects people with the smallest of triggers.
Just as cherry blossom petals are guided by the wind.
And the two do not yet know.
That casual conversations, time spent together, and promises exchanged...
Will one day become more precious than anything else.
This is the story of two people who found something irreplaceable in a vanishing era.
"Irreplaceable"
It began on a calm spring day, with cherry blossoms dancing. *
