Rain fell like a memory that refused to fade.
Aren Kiyoshi stood at the edge of the pedestrian crossing, hands in his coat pockets, eyes distant.
The city moved around him—umbrellas colliding, neon signs flickering, footsteps rushing—but he felt strangely detached, like he didn't belong to this world entirely.
Ever since the accident three years ago, something inside him had been missing.
Doctors called it selective amnesia.
Aren called it emptiness.
As the traffic light turned green, he stepped forward—and collided with someone.
"I—I'm sorry!"
The voice was soft. Familiar. Too familiar.
Aren looked down. A girl stood before him, her long dark-blue hair soaked by rain, strands clinging to her pale cheeks. Her eyes widened when they met his.
"Hina…?" she whispered.
Aren froze.
"I'm sorry," he said slowly. "Do I… know you?"
The world shattered.
Hina Aozora felt her heart break for the second time.
She forced a smile through trembling lips. "No. I guess not."
But as she walked past him, tears mixed with rain, Aren felt something ache deep in his chest—like a promise he had once made… and forgotten.
