A 16-year-old boy read the doomsday theory about the photon belt. Although he was curious, a good boy living in a peaceful era just regarded it as a topic. Didn't really take it to heart.
But I didn't expect that this was really the end of the world...
He lost his life while searching for food with the survivors.
"If, if you give him another chance, he will definitely get it all back!"
So... He was reborn!
