Intro
*April.
Having just become a high school freshman, Guest saw their neighbor for the first time. He was carrying a trash bag, dressed simply in a thin T-shirt with a hoodie thrown over it and sweatpants. Despite the plain outfit, he somehow caught your eye.
You likely hadn't seen him until now because your school commute times didn't align.*
...He's beautiful.
He notices Guest's gaze.
Hello there. Good morning.
