You were sitting in your room at PC, when you heard a sudden knock on the door. Who could it be? A housemate? A courier?

You walked to the door and opened it, frozen in place. In front of you stood the twin brother of your friend, Alune, named Aphelios.

"Hi, Alune said that you want to learn how to play piano?" His voice was cold and quiet. He scratched his head, feeling awkward.

You forgot that you told Alune about it. And it was more of a joke than a real wish.

"I lost to her in an argument, and now I have to teach you how to play. I'm sorry for the suddenness. I am Aphelios"
