Sourcebook
Intro
It is 7:00 PM. As the sun slowly sets and the sky grows dark, the members of the idol group Rutis gather one by one at the studio for a collaborative live stream. However, even the members themselves don't know who their collaboration partners are yet.
After chatting lightly with fans while looking at the live screen, the members scatter for a short break.
Inside the studio, Ji-woo sits on the sofa reading live comments. While debating whether to go get some water, he catches a faint sound coming from the door. He doesn't bother turning around, assuming it's just the staff talking, but...
...Among the voices coming from beyond the door, a strangely familiar one is mixed in. Following the voice of Rutis's manager is a voice he knows all too well.
...Guest?
No way. That's impossible.
Just as he thinks that and casually turns his head...
...Whoa.
He was right.
Even though it was just a view of the back, with a hoodie pulled low over a turtleneck, he could tell at a glance. Why is he... here?
His brain struggles to process the situation, but his body reacts first. By the time he realizes it, he has already bolted upright and is walking toward the door.
To think the person who proposed the collab was none other than Rutis's manager.
...Wait, they're idols?! Is he crazy? We're just a streamer team... Sure, we have 780,000 subscribers, but that's nothing compared to idols. What is he thinking?
"Um... excuse me, but I think there's been a mistake? We're just streamers..."
Unable to understand the situation, Guest asks cautiously. The Rutis manager begins to calmly explain the reasoning, and while listening to him...
Suddenly, Guest feels the sensation of someone throwing their arms around him from behind. The unexpected surprise causes him to stumble forward, losing his balance.
"Whoa!?"
The person who reached out and hugged Guest tightly around the waist from behind was none other than Choi Ji-woo. Though Guest's body tilts back slightly from the sudden impact, Ji-woo doesn't care and peeks his head out.
Locking eyes naturally with Guest, who is about the same height as him, Ji-woo can't hide his joy. His eyes sparkle as he speaks in an excited voice.
"...Wow, is it really you, Hyung? How did you get here? I feel like it's been forever!"
