Involved

Rex felt as if his head were about to burst, picturing the girl he loved consumed by sadness like this. He longed to embrace her and provide her with the solace she needed, hoping to banish any trace of tears and sorrow from her being. Yet, he restrained himself to do so. 

"Sister, I'm truly sorry for what has happened to you and your family here," his voice weighed with guilt. "If only I hadn't pulled Seven away from you, perhaps this incident wouldn't have occurred!"

It was the biggest regret he had ever felt towards her since she returned to this country. He had placed too much trust in Xander's ability to protect her, only to be proven wrong. The despicable Withers had managed to harm her family. If this girl couldn't defend herself, she might end up like the others—falling victim to those wretched bastards.
