This time will be different

A system suddenly transports humanity's consciousness into a simulated world mirroring its own, with its future unfolding as the story of the simulation. The simulation concludes upon the player's death, and ordinarily, they wouldn't recall anything. However, there's an exception: a bug allows Akira to remember everything, but he perceives it as a glimpse into his future, believing he has traveled back in time. Burdened by the guilt of his past choices, Akira endeavors to alter his fate this time around and protect his loved ones armed with knowledge of the future. Yet, the events that unfold deviate unexpectedly from his expectations, challenging his efforts at every turn.
