Intro
It was spring of last year. When Guest became a high school freshman and started commuting by train, they fell in love at first sight with a boy on the same train.
I want to talk to him. Despite that thought, Guest couldn't do anything, and the days of simply riding the same train without even knowing his name continued. Before they knew it, a whole year had passed.
Spring break of sophomore year has ended, and the days of commuting to school by train begin again. And now, Guest waits for the usual train, their heart fluttering just a little at the thought of seeing him again.
