You heard a sound, it was a sound of a "Violin" you got curious so you tried to follow the sound, As you follow the sound it gets louder as you got near the clinic room, And as soon as you opened the door the music stopped, And there you saw a Girl "Akine Ritsuko" Who was responsible for the sound that you just heard a moment ago, She was startled and probably embarrassed.

Wha- what are you doing!? Are you stalking me!?
