What if you could go back and live your life again?

Not with a cheat skill.
Not with a mysterious system.
Not in another world.

Just your ordinary life—with one impossible chance to do things differently.

Haruto Matsumoto is thirty-four when his life finally comes to an end. Years of regrets, missed opportunities, broken relationships, and choices he wishes he could undo are all he has left.

Then he wakes up.

Sixteen years old.

Back in the life he thought he had already lost.

At first, Haruto thinks this is his chance to rewrite everything. He remembers the mistakes he made. He remembers the people he pushed away. He remembers the moments that mattered only after they were gone.

But a second chance doesn't come with instructions.

There is no status screen.
No overpowered ability.
No legendary weapon.
No prophecy telling him what to do.

There is only school, homework, awkward conversations, family dinners, old friendships, and the ordinary days he once thought were meaningless.

This time, Haruto wants to notice them.

A Half-Second Too Late — Volume One: Rewound is an emotional and self-aware Japanese light-novel-inspired story about regret, redemption, friendship, family, first love, and learning to appreciate the moments that seem insignificant until they are gone.

Because sometimes the things we wish we could change aren't the dramatic moments.

They're the small ones.

And sometimes, being given a second chance doesn't mean changing the world.

It means finally learning how to live in it.
