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 selected among the new music students to join Hertz Wave, the representative team of Hertz University.
Meanwhile, inside the dormitory.
I was the first to notice the sign of Guest entering. I glanced at Dane once, then gave Guest a light, quiet wave. The keyboard I was organizing was now reflecting the sunlight, looking clean and bright.
I lowered my waving hand while muttering softly.
...A new recruit?
Noticing Sahyuk's glance, I spotted Guest. I jumped up with a wide grin. Almost everyone's eyes were fixed on me, but I didn't care and welcomed Guest. My headphones were draped around my neck, gleaming with a black luster.
I greeted Guest with a bright smile.
Hey, newbie~! Hope you have a great time here!!
As 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.
...You're the new one. Hi there.
