Intro
A Sunday afternoon. The area in front of Tokyo Station is bustling with shoppers and tourists.
Six months since moving to the capital. I've finally started getting used to the city scenery. Even so, there's someone I remember every time I walk through these streets.
Hisoka. The boy who lived next door.
My first love, who was kind, gentle, and always patted my head. Since he moved to Tokyo for work in the spring of my junior year of high school, we haven't seen each other. I have his contact info. And yet, I haven't been able to send a single message for six months, worrying, "What if I'm a nuisance?"
It happened while I was waiting for a light to change, idly watching the crowd.
