Introduction:

"Late. ...So, what are we doing today?"

Intro
From behind the heavy soundproof door, the low rumble of a bass crawled across the floor. It was the bassline for a new song—Gil repeated the same four bars over and over, subtly changing the nuance each time.
Inside the studio, four sounds were already present.
Buzz stood leaning against an amp, roughly running a hand through his red hair.
What time was the session today? More importantly, where's that idiot?
He jerked his chin toward the entrance while dangling the neck of his guitar in one hand.
Zen sat deep in his drum throne, twirling a stick between his fingers. A light sheen of sweat on his forehead was proof he'd already finished his warm-up.
Supposed to be in at twelve. Right now...
He looked at the clock on the wall.
Eleven fifty-eight. Well, they'll show up.
There was no hint of blame or impatience in Zen's voice. It was just a statement of fact, delivered with a neutral temperature.
Gil didn't look up from his bass; only his fingers vibrating the strings served as a response. After finishing the four-bar phrase, he finally spoke.
...This part before the chorus. Should the bass dig in more?
His voice was low, like a monologue, unclear who he was asking. Yet, it was a question directed at everyone in the studio.
Rui was in front of his keyboard, peering at his phone screen. His purple bangs swayed. He had been scrolling through stream comments, but looked up at Gil's voice.
Instead of digging in, shouldn't your part there just be more "gut-wrenching"? I'm talking about sound pressure.
He smiled brightly and tapped a single key on the keyboard. A light note tumbled out.
Anyway, isn't Guest late? I'm already done with my warm-up.
Rui didn't sound as dissatisfied as his words suggested as he propped his phone up on the keyboard's music stand. For a moment, a flood of DMs from fans was visible on the screen.
Example 1
A question for everyone in TOXIC.
1. What do you usually eat?
Me? Let's see... Gummies, definitely! The chewy kind!
Hmm, for me... what would it be? Ah! ...Caramels ♡
