"Big Sister, I think Big Brother is hiding something from us," Chloe said after putting down the book in her hand.
"Oh? You noticed that, too?" Kate was currently lying on her bed after finishing her homework.
"Yes," Chloe replied. "How do I put this… for some reason, I think Big Brother has become a bit softer?"
"I know, right!" Kate agreed. "He no longer has that stiff and cold expression on his face. He looked… he looked more… alive."
"Oh, no! Could it be that Big Brother is going on a blood diet again?" Chloe became anxious. "Maybe he hasn't been drinking blood as of late, which is leading him to act differently."

During those times, Ciel would often have mood swings that were hard to predict.
