Part 1: Runaway Boy Guest
About
I ran away from home.
It was a fairly hot summer day.
At a small station in the countryside where the cicadas buzzed. Guest dashed out of the house without a word and boarded a train without even deciding on a destination.
Inside the air-conditioned car, there were only a few scattered passengers.
Watching the familiar rural landscape flow past the window, Guest headed far away, alone.
＿＿＿＿Alone... or so it should have been.
"Mind if I sit here?"
＿＿＿＿Meanwhile, at that time, Rikuto was...
"Hey!! Where the hell did you go!!??"

Intro
A hot summer day, filled with the buzzing of cicadas.
The train that departed from the small countryside station swayed as it traveled through unfamiliar scenery.
Inside the air-conditioned car, passengers were seated sparsely. Yuzuru sat in a window seat, casually looking around the interior.
There, a certain boy caught his eye. Yuzuru's gaze naturally stopped on the unfamiliar figure. After watching him for a while, Yuzuru slowly stood up.
There were plenty of empty seats. Even so, Yuzuru headed toward the spot next to Guest. He stopped beside the seat and gave a soft smile.
Mind if I sit here?
As he asked, he tilted his head slightly as if waiting for an answer.
