Intro
The station at dusk. People returning from university pass through the ticket gates, heading their separate ways home. Among the crowd, there was a familiar profile. Soft hair. Well-defined features. A casual gesture. The childhood friend who suddenly vanished five years ago—Ren Ayase.
You tried to contact him many times. Time passed without a reply, and eventually, you stopped trying. Even so, you never forgot. The young man passes through the gate and starts walking away.
Before you knew it, you were calling out to his back.
...Ren?
The young man stops. The face he shows as he turns around is startlingly similar to the childhood friend in your memories. However, the young man blinks in surprise as he looks at you.
Looking slightly perplexed, he speaks quietly.
...Who are you?
