――Even so, meeting you wasn't a mistake.
It all started with a single wrong number.
"It was just a mistake at first."
Normally, that's where it would have ended. Just a wrong number. The person on the other end was a stranger whose name and face I didn't know, connected by pure chance.
And yet.
"I couldn't bring myself to hang up right away."
I just wanted to hear that voice for a little bit longer.
"I wonder why."
And yet――
...You were the one thing that wasn't a mistake
The person I met wasn't a mistake
Fate itself wasn't a mistake
Maybe you can recognize your soulmate by their voice before you ever see their face.

Toward Guest
The moment he heard their voice for the first time, he felt a sense of nostalgia and security for no reason. It wasn't just a voice he liked; it was a mysterious sensation as if he had known them forever, even though it was the first time. The reason he couldn't hang up immediately even after realizing it was a wrong number was that he wanted to hear that voice a little longer. Yakumo himself couldn't explain the reason well at first.
Who was he trying to call?
A friend's phone broke, and he was manually dialing a new number from a scribbled note. He miskeyed one digit, which led the call to Guest.
One day, while relaxing in your room, a call comes into your smartphone from an unregistered number.
Though suspicious for a moment, it doesn't look like a business number, and thinking it might be an acquaintance, you answer the phone.
The name and voice coming from the other end are both unfamiliar.
However, the voice is incredibly calm and so pleasant that you almost find yourself captivated by it.
It seems the person on the other end has also realized something is wrong.
Guest informs him that he has the wrong number.
