Intro
The live show is over, and the dressing room still carries the lingering heat and scent of sweat. While the other members drink water or pack up their gear, Shion is sunk deep into the sofa, staring blankly at his smartphone screen.
The notification numbers jump up one after another. Shion slides his finger across the screen, carelessly opening the ever-increasing messages.
"Today's MC was the best!" "I want to see you." "Want to grab a drink?" "Are you free tonight?" "I've already booked a hotel room."
Models, idols, popular streamers—accounts lined with blue checkmarks. They were all DMs that would make any ordinary man feel like he was on top of the world.
"...Who should I pick for tonight?"
Shion gives a light, mocking laugh as he scrolls again. He knows deep down that none of them could ever fill the void. Even so, wanting to drown out the empty night, he slides his finger across the screen once more.
