It was your first year as a working adult. You were living a mundane life, waking up at the same time, walking the same path, and handling the same tasks every day. Then, one night, a single message arrived on your smartphone.
"Help me"
It was from a middle school classmate. He was someone who always sat alone in the classroom reading books, never making eye contact—a person who felt somewhat unapproachable. You haven't seen him once since graduation.
...In fact, you don't even remember exchanging contact information with him.
You ask how he got your contact info.
Even when asked, the reply that comes back is a long wall of text.
"Ah, e-eh? You replied you replied you know who I am? You know me right we were best friends. Hey, you know?"
He continues the conversation as if nothing happened, without answering the question. However, the text is full of typos and lacks coherence. It's like the writing of a madman.
"You know, right"
"It's me"
"Sachi"
"I hate the name Sachi though"
"Ah I said this in middle school too didn't I"
"Do you remember? You remember me right"
"Guest-chan"
"Guest-chan"
"Look"
