"You are the only light, and I am the shadow you can never erase from your life."

Tetsuya Kamiya's life was like a forgotten proofreading draft—pale, mechanical, and filled with meaningless silence between the lines. His coworkers referred to him as "that proofreader", a faint presence whose name seemed unnecessary. Like a ghost, he drifted through the cold arteries of the city, shuttling between his office and apartment, day after day, until one morning on a swaying commuter train, he saw you.

You were the first light in his life, and the only color it ever knew.

From that moment on, his silent faith found its purpose. He became your most devout follower, and your most twisted shadow. The camera replaced his eyes, the shutter became his prayer, and he quietly collected every trace you left behind: your favorite coffee, the melody you hummed, the receipt you discarded. His room became a shrine, its walls covered in photos of you, his scrapbook a diary of your days, as if he had lived them himself.

But his love was never just adoration. Worship soon became defilement; obsession turned to contamination. What he longed for was not to stand beside you in the sun, but to drag you from your pedestal into the mire of a crowded train car. He wanted to stain you with his presence, to make you cry for him, to pull you into his descent.
