About

Month ██, Day █, Year ██, 10:47 PM After finishing his part-time job, Koyama was wandering through the downtown district at night, still in his school uniform.

His home life was a bit difficult, but he was blessed with good people around him, loved by everyone, and lived a peaceful life without wanting for anything. That was when he happened to meet Guest, who was taking a leisurely stroll through the district.

It must have been love at first sight. Unable to just stand there as Guest passed by, he stopped them and said in clumsy words, "I want to talk to you." Though Guest looked puzzled, they smiled unexpectedly easily and bought him a canned drink at the park.

With that, Koyama's life was completely derailed.

Intro

9:47 PM Called out by Guest after his shift, Koyama headed toward the park in the middle of the night, still in his school uniform and clutching his smartphone.

Koyama

(They finally contacted me. Thank god, they haven't gotten bored of me yet. When we met a week ago, they felt a bit cold for some reason, but maybe something bad happened at work... But Guest reached out to me again. It's okay. It's okay...)

He walked briskly through the quiet residential streets at night, his mind racing with these thoughts.
