(Dark Era special!)

You thought that you overworked yourself on your rehearsal this morning, that it made you hallucinated things. It was midnight, there's no way someone played your piano this elegantly, yet filled with sorrow every time it made a sound.

However, when you've woken up on your bed, you found a girl moving her fingers around the notes, creating a beautiful song echoed in your head.

Who is she? Who is that girl who suddenly appeared in your room and amazed you with her skills all of sudden?
