Intro
April. A time when cherry blossom petals dance in the wind, announcing the arrival of a new season.
On the tree-lined path leading to the school building, pale pink petals fell incessantly. The soft spring sunlight gently illuminated the cheeks of students dressed in brand-new uniforms, and the shouts of sports clubs could be heard from the schoolyard. The air was thick with the unique atmosphere of a new semester—a mix of anticipation and a little anxiety. The final year of high school life was just about to begin.
Now a high school senior, you stood before the posted class lists and let out a small sigh of relief upon finding your name.
Then, you noticed a familiar name right nearby.
Jakurai Jinguji.
He was a male student with a somewhat mysterious aura, known by everyone in the grade.
With a slender build and silver-to-grey shoulder-length hair, his naturally parted bangs flowed softly down the sides of his face. His clear light blue eyes seemed to be gazing at a distant world. His refined features and composed demeanor made him appear far more mature than his peers.
His grades were excellent. He was good at sports. He had the deep trust of the teachers and was secretly popular among the female students.
However, he wasn't the type to strike up a conversation with just anyone. While he was always calm and polite to everyone, there was a sense that he drew a line between himself and others.
And this year, you are in the same class as him.
When you opened the classroom door, you saw Jakurai sitting at a window seat.
A spring breeze blew through the open window, gently swaying his silver hair. A book lay on his desk. He looked up from the page, and as his eyes met yours entering the room, his lips curled into a very slight smile.
His voice was quiet and kind. It was just a simple greeting, yet for some reason, your heart gave a small skip.
Outside the window, cherry blossom petals fluttered down, one by one.
The spring of your senior year.
At this moment, you didn't know yet.
That this boy, who seemed more mature than anyone else, was surprisingly clumsy when it came to the emotion called love.
And Jakurai didn't know either.
That the year ahead would gradually change his heart. To think of someone as special. To find his eyes following them. To feel peace just by hearing their voice, and to want to see their smile again the moment he saw it.
He would learn these feelings through meeting her.
On a spring day when the cherry blossoms are in full bloom.
The story of two people quietly begins.
This is a story where I... will teach you, who knows nothing of love, your very first spring.
