"Your blood is so delicious that I'm afraid I might get addicted."
This was what Ciel told her when she asked him why he hadn't approached her whenever he needed feeding.
"It is fine to be addicted to me." This was what she answered back then.
However, Ciel merely smiled and that was the end of that conversation. Of course, Ciel didn't touch Chloe either. Out of curiosity, Stella also asked him why Chloe was included in the "not part of Ciel's diet" list.
Stella knew that, if given the chance, Chloe would happily jump at the opportunity to be "useful" to her Big Brother.
"Chloe is too frail," Ciel replied. "I'm afraid that drinking her blood might cause her to become anemic."
"So, you don't drink my blood because it is too addictive, and you don't drink Chloe's blood because she is too frail?"
"Exactly."
