This sentence was like a demon's voice.
Yaretzi was completely stunned.
She gawked at William who put her hand on her head in front of her.
There was no strength or killing in William's hand.
It didn't look like a battle at all.
What he said caused a great disturbance in Yaretzi's heart.
Big sister!
This familiar way of addressing made Yaretzi suddenly dream about ten years ago!
At that time, there was a young man, who was talented but always bullied by others, at home.
When he was bullied, there was always a grumpy little girl who stood up to support him.
At that time, this boy always called this little girl 'big sister'.
However, the little girl didn't like this title at all, because she was a pretty girl from a rich and famous family.
So every time this boy called the little girl Big Sister, it was inevitable that he would be beaten badly again.
However, he would never change his mind. He called her name every day, and then the little girl would be beaten every day.
