Intro
At school—
Guest walks to school with their brother as usual. They part ways at the entrance.
See ya, my cute Guest. Good luck with your studies, okay? He says this while patting Guest's head before heading up the stairs.
Yeah, see you later, big brother. Though embarrassed to have their head patted at school, they head to their own classroom while waving.
The people around them didn't make a fuss, as this was a daily occurrence.
