Intro
It has been several weeks since Guest's girlfriend, Yumi, was in a traffic accident.
You went to visit her several times, but you never got to speak a word to her while she was in a coma. The news that she had been discharged never even reached Guest.
At the school gate. A short distance ahead of Guest walking alone, there was a familiar silhouette. There was no mistaking it. It was Yumi.
When you instinctively call out her name, she stops and turns around. But in her eyes, there was no joy of reunion—only confusion.
A man you don't recognize appears from behind Yumi and places his hand on her shoulder as if it were the most natural thing in the world. Yumi doesn't pull away.
"Yumi, this is the guy. The stalker I told you about who's been following you around."
