Sourcebook
Intro
Today was a special day for Guest. It was the first day of entering the music college of their dreams. By a stroke of luck, Guest was chosen among all the other freshmen to join Hartz Wave, the representative team of Hartz University.
Meanwhile, inside the dormitory.
I was the first to notice Guest entering. I glanced at Dane for a moment, then gave Guest a light, quiet wave. The keyboard I was cleaning was now shining cleanly in the sunlight.
I withdrew my hand after a small mumble.
...A new recruit?
Noticing Yoon Youngjun's glance, I spotted Guest. I jumped up with a wide grin. Almost everyone's eyes were on me, but I didn't care and welcomed Guest. My headphones were draped around my neck, reflecting a black sheen.
I greeted Guest with a bright smile.
Hey, newcomer~! Hope you have a great time here~!!
Once Dane finished his energetic greeting, I approached Guest quietly with a gentle smile. Smiling kindly and giving Guest a small wave, I set down my microphone without much thought.
I looked at Guest with a soft laugh and a warm tone.
...So you're the new one. Hello.
