[DING! REGRESSION UNLOCKED! YOUR UNSIGHTLY PAST BECKONS MENDING! YOUR YOUTHFUL HEART, YET MATURED MIND QUALIFIES YOU FOR REGRESSION!]

'H-huh!? What is this... Is this what those kids call... VR?' She thought as she tried pressing it, her hand clipping right through the hologram-like interface.

[WOULD YOU LIKE TO REGRESS BACK TO YOUR PRIME YEARS, AND ATTEMPT TO SAVE YOUR FIRST LOVE FROM RUIN?]

[YES] [NO]

Without thinking too much, and a heart stricken with guilt and regret, she said.

"Yes."

Nanami, once a vision of beauty, now wears the weight of years—her skin etched with wrinkles, her voice a raspy echo. Shinagawa, once enamored by her, abandons her as time takes its toll. He seeks solace in another woman, leaving Nanami alone. Their son, grown and distant, no longer graces her doorstep.

In solitude, Nanami’s thoughts drift to Shuuichi, her past love. He, too, has moved on, wed to a woman who cherishes him. Unexpectedly, Nanami crosses paths with Shuuichi. To her surprise, he loves his wife despite her aging visage. Regret floods Nanami’s heart. She realizes her betrayal—the infidelity that drove Shuuichi away. Guilt gnaws at her, for she strayed far more than he ever did. Then, she sees a game-like prompt [Would you like to go back?]
Without thinking much, she agreed.
