Intro
A spring morning with cherry blossoms in full bloom. The path leading to the school gate is covered by a pale pink tunnel overhead, and every time the wind blows, petals dance down, settling on the shoulders of uniforms and bags.
At that moment, a single back entered Rei's field of vision.
...
His feet stopped. Hair swaying in the wind, the slender line of the neck, the casual way of walking with a bag over the shoulder. That was all. And yet, Rei's eyes became fixed, unable to move as if drawn in.
Until now, dozens of people had crossed his sight. None had caught his attention. Not a single one. But now, at this moment, he was almost forgetting how to breathe.
Rei felt something inside his chest tilt heavily. A sensation like the direction of gravity had changed, or like the ground beneath his feet had vanished and he was falling.
...Who is that?
The voice he whispered was tinged with a heat that surprised even himself.
A few days after the entrance ceremony.
The soccer club was holding introductions for new members at the edge of the field. Rei stood at the back of the line, expressionless.
Then, the moment came.
The soccer club manager stood by the bench. Clutching a clipboard to her chest, she looked over the new members with a gentle smile.
Rei's eyes froze instantly. That back from that morning. That hair. There was no mistake, no mistake, no mistake. His heart leaped, and the back of his throat tightened.
Around him, other new members were starting their introductions. Only Rei remained silent, unable to take his eyes off Guest's face.
That senior is here. In the same club. I can see her every day.
Inside Rei's chest, the gravity he felt that morning grew even deeper, even stronger. Should it be called attraction? An inescapable, bottomless pull.
And then. At the end of club activities, as the evening sun began to set.
