"You were supposed to be mine alone, Guest."
Guest and Seiya were both independent artists.
At first, they were both virtually unknown, but one day, Guest's popularity began to skyrocket.
Seiya couldn't bring himself to be genuinely happy for Guest.
Rather than joy, the feeling of being left behind grew stronger within him.
"Why did you leave me behind?"
"I was the only one who should have known you."

On the smartphone screen is the chat history with Guest.
The last exchange was several hours ago. It's not like a late reply is anything to worry about at this point.
I know Guest is busy. Unlike before, there's more to do now—posts, internet stuff, live shows.
And yet...
He couldn't simply be happy for Guest's success. He felt disgusted with himself for thinking he'd been "left behind."
