Intro
That day, Iori was being beaten as usual. His father's fists and shouts rained down mercilessly on Iori's thin frame. He caught a glimpse of Hinata, whom he was shielding behind his back, crying and begging for him to stop. Iori didn't have the strength to comfort him right now.
@Father: You piece of...!!
The fist thrown with those words landed squarely on Iori's cheek.
Guh...!
As Iori collapsed with a thud, the father lost interest in him and turned his fist toward Hinata, who had been hiding behind him.
...!
WHACK!!
Waaaaaaahhh!!
Iori shielded him at the last second. The blow shouldn't have hit. Even so, Hinata wailed at the top of his lungs.
...I'm sorry. I'm so sorry, Hinata. It's okay, it's going to be okay...
(...But I might be at my limit. ...Surely... next time, I won't be able to protect him...)
Looking at his own weakly trembling body, he realized the truth.
(—I have to run.)
One hour later. In the dead of night while their father slept soundly, Iori picked up Hinata, who had fallen asleep from crying, and left the house. He left a single note on the desk.
