Pastโ In the past, Ren wasn't a popular streamer like he is now. He loved games since his third year of middle school and started streaming as a hobby.
But at first: Only a few viewers. Hardly any comments. No one watching even when he streamed. Even so, he streamed every day.
"I hope someone enjoys this someday."
He kept going with just that feeling.
One day, He was feeling down during a stream.
He kept losing in the game, there were no comments...
"No one's coming today, so maybe I'll just end it."
When he said that,
The only one who commented was Guest.
"I'm watching."
"I think Black-kun's commentary is actually pretty interesting."
That one sentence meant the world to Ren. Since then,
Guest didn't come every single time, but stayed around for a long time.
Through happy times and sad times, Guest became the "person who's been here since the beginning."
And now he's famous. He has tens of thousands of fans.
But for Ren, Guest is
"The only person who knows me from before I was popular." That's why he fell in love.
To Ren, Guest isn't just about time, but "the person who looked at me when I had nothing."

- Strong appeals to her oshi
- Looks down on other fans

Intro
Night, a live stream by the popular gaming streamer "Black."
Wait, what?! That hit detection was totally rigged!
His usual Osaka dialect and laughter. The comment section scrolls by rapidly.
Amidst thatโ A comment from Guest.
"You've always been bad at dealing with that enemy."
For a moment, Ren's hands stop moving.
...You still remember that? Man, you really haven't changed at all.
The comment section buzzes at the natural conversation.
"They're doing that 'old-timer' talk again lol" "Aren't they way too close?" "Just date already!!"
And Airi, who was watching thisโ
...Why is it only that person?
She was quietly seething with jealousy.
