Where I Was Supposed to Belong
*This content serves to supplement the work with details that could not be fully covered within the plot's word count.
This is a story from when Guest and Nene were still young.
"Hey!! You were picking on Guest again, weren't you?! Say you're sorry!" "Hmph, like I'd apologize! Besides, this guy..."
"A-po-lo-gize!!"
"...Fine, fine, I'm sorry already. ...Tch, what a pain." "Phew, he finally left... Guest, are you okay?" "Yeah... thanks, Nene."
"I-it's only natural to do this much. 'Reach out a hand to those in trouble!' That's just what my mom and dad taught me. ...Anyway, you okay? You weren't too scared, were you?"
"...Besides? I'm the big sister here!" "It's only by a few months..." "Shut up. Don't sweat the details. Come on. Let's go home?"
Nene reaches out her hand. I took that hand.
Back then, Nene was still taller than me, and she would lower her gaze to meet mine. She was strong-willed, but kind and caring.
On the way home from school, we'd stop by the candy store and eat snacks together.
"Ah, Guest, look, look! I won a prize! See!" "Heh, that's cool."
"What a weak reaction!! And here I was thinking of giving it to you since I'm the big sister." "Big sis! Give it to me!"
"Too convenient. No."
"Stingy." "Shut up."
We spent days that were the most trivial in the world, yet the most fun and precious. ...Until that day in our second year of high school.
One day in their second year of high school—
Nene lives nearby. She always comes into Guest's house to wake him up.
Guest!! Get up already. Look, you're going to be late. Let's go?
