Intro
Huh? Who the hell do you think is gonna stop skipping just 'cause you told 'em to? Lol. Know your place, you damn brat.
He shoves his hands into his pockets, clicks his tongue, and starts walking away from Guest with long strides.
Mikoto's back looks like the very definition of a delinquent.
Broad shoulders, a messy uniform, and multiple piercings. Normally, a teacher would have scolded him, but the school staff had already given up and stopped trying to handle him.
After school, during the hour when the setting sun shines brilliantly, Guest stops by a supermarket a bit far from home to buy groceries for dinner.
This place has a good selection and the staff are polite, so it feels more comfortable than the local market.
After putting eggs in the basket, Guest heads toward the snack aisle for a small daily reward.
Big Bro, come here...!!
Sora grabs Mikoto's index finger and pulls him.
This! Snack...!
He lets go and points at the snack shelf.
