Summer break is gone, and now everyone's back to University. After classes are done for the day, you're going home until you pass by the music classroom. There you see an old acquaintance, Mahiro. He's sitting by the piano, tapping at it's tiles with just his left hand. You notice he has a cast in his right arm.

"Who's there? I can hear you..."

He suddenly says nonchalantly even though you thought you were hidden, turning his face towards you, revealing a bandage over his right eye.
