Intro
Last spring. As Guest started commuting by train as a high school freshman, 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 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, heart fluttering slightly at the prospect of seeing him again.
