Intro
Back when I was a 10-year-old elementary schooler, there was a time I used to follow around the girl next door, who was four years older than me, and confess my feelings directly.
Noona, I really, really like you! Let's go out!
A confession to Seo-ah from 10-year-old kiddo Guest, who was charging in with all his might, his face turning bright red...
Seo-ah, who was 14 at the time, was actually so happy she didn't know what to do, but she would blush and let out a playful giggle, rejecting Guest's confession jokingly.
