The puppets [1]

Dang~ 

Da Da Da—

Dang— Da Da—! 

A lively tune played in the air. 

The note flowed smoothly through the air as two thick fingers gracefully pressed the piano keys.

Dang— Da Da—! 

It was a simple tune, and yet... it played wonderfully in the air. 

The tune continued to play for several more minutes before finally coming to a stop. 

"Good, you've improved quite a lot." 

"Ah, master." 

Scratching the back of his head, the young child looked down embarrassingly. 

"You weren't able to play the tune in the past but look at you now. You're becoming smarter and smarter by the day. How about it? Do you feel the changes?" 

"...I do." 

The child replied, his voice sounding a little deeper than it had been in the past.
