Chuya's Life Simulator

After fainting from hunger and waking up again, Nakahara Chuuya discovers that he has a life simulator that can simulate his future.

He thinks he's about to reach the pinnacle of life, but then realizes that no matter what he chooses, he cannot escape the fate of having his friends killed at sixteen by a brother who appears out of nowhere.

Little Nakahara Chuuya: Is this even fair?

Nakahara Chuuya falls silent, thinks it over again and again, suddenly understands, and makes a firm decision!

Nakahara Chuuya: As long as I run fast enough, I won't have any friends. And if I don't have any friends, my brother can't kill them.

As for the friends and family who learn the reason

The Vongola boss ten years from now smiles indulgently: Given Chuuya's circumstances, it's understandable that he would make that choice. Still... he must feel a little frustrated.

The white-haired, blue-eyed high schooler looks utterly arrogant: Come on, I'm the strongest! Some creepy brother is no match for me!

The pink-haired boy with a lollipop on his head suddenly gets it: I see. No wonder you broke free of my suggestion and ran all over the place.

Content warnings:

1. Everyone's relationships are platonic. There will be no couples.

2. Chuuya's circle of friends includes many people beyond those mentioned in the blurb.

3. This is a crossover. I'll add more details as I think of them.

Theme: Staying cheerful and optimistic
