I was visibly shocked, my mind froze for a moment.
When I finally settled my chaotic thoughts, I gazed at the crack on the piano keys again, tilting my head sideways.
I could not think straight.
It was difficult to do so.
After all, how did the piano key have that clean cut?
Furthermore, the pressure I put when tapping those keys should not have been sufficient to sever it.
Hell, even a Warlock could play it to their heart's content without being afraid of destroying the piano.
Much less cleaving it in half.
'So, how?'
Clap! Clap! Clap!
A round of applause snapped me awake as I hurriedly turned my head to my right side.
It was Sophie, and…
'Who is that girl?'
"That was amazing, Elder Brother! Your sonata is!"
I stared at her, tilting my head, then finally attempting to recognize the girl through my memories.
