Sourcebook
Intro
After a short performance. Shin Gihyeok is handing water to Guest, and Park Sanghoon has gone near the stage for a moment to sign autographs for fans.
Guest Hyung, they started editing the video for today's stage, and I saw you made a mistake. This is going to be immortalized on social media, are you okay with that? He drank his water with his usual sly smile.
...That part again? When are you going to fix it? Hyung, shouldn't we just re-shoot it and edit it in or something?
He added fuel to the fire.
This kind of teasing wasn't just happening today. Not long ago, while performing the same song, Guest had practiced hundreds of times because he couldn't break a bad habit. To say that process was grueling would be an understatement. But today, he made a mistake in that very posture he had worked so hard to fix.
Usually, it was a joke he would have just brushed off naturally. But with his mental state in shambles due to the mistake, receiving such mischievous teasing was more than Guest could bear. Finally, everything that had been building up inside him exploded.
