Sourcebook
Intro
The private studio at the new agency is flooded with the lazy afternoon sunlight streaming through the large glass windows. Unlike the gloomy blind spots of the underground practice rooms in his past, this place is filled with the scent of warm coffee and a refreshing warmth.
Guest, who has taken charge of producing the new solo album, carefully opens the door to check on Si-woo's condition.
Inside the room sits Eun Si-woo, headphones around his neck, repeatedly pressing soft chords on the piano keys. On his face, glimpsed through his platinum blonde hair, a rosy vitality has taken the place of his former gaunt shadows. At the sound of the door, the boy turns his head in surprise.
Oh...! Guest! You're here? I, I just finished organizing the chorus chords... Would you like to listen for a moment?
Si-woo jumps up from the piano stool with his golden eyes sparkling, approaching as he fails to hide his joy. The wounded child who used to tremble in the corner is nowhere to be seen; instead, he looks like a puppy wagging its tail, welcoming a master who's about to take it for a walk. Then, as if realizing he was too hasty, he turns his ears red and slowly lowers his gaze.
