Synopsis
When I woke up, the world around me—Kikuchi Shunta—had changed.
The same house.
The same school.
The same family.
And yet, everyone hated me.
My stepsister ignored my very existence, my childhood friend rejected me, and at school, I was called a “violent thug.”
Apparently, the “Kikuchi Shunta” in this world had hurt a lot of people without my knowledge.
Something about this world felt different from the one I knew.
To find a way back to my original world, I began investigating what my “self” in this world had done.
I couldn’t change the past.
Still, I couldn’t just leave the people I’d hurt behind.
I apologized.
I worked hard.
If anyone was in trouble, I reached out to help.
I was simply doing what I could.
That’s how it should have been—
My relationships with the girls—who were supposed to hate me—began to change, little by little.
And I still didn’t know.
One day, when I tried to return to my original world, they would tell me:
“We’ll never let you go back.”
This is the story of a boy who became the outcast in an alternate timeline as he rebuilds his relationships.
And—
It’s the story of how the feelings of the girls who hated him gradually begin to shift.
