"Sweetheart, I've wronged you. They are them, and you are you. You are different from them." Fourth Master grasped her hand.
Ye Zao refused him: "How am I different? All your women, all of us come from the selection process..."
"Oh, I forgot, I'm not even as good as them. I'm not from the selection process; I was sold here." Ye Zao thought, feeling even worse.
"Why are you thinking about these things? When have I ever disliked you? Honestly." Fourth Master frowned: "In my heart, you are the best. Be good, don't make trouble, take care not to upset yourself."
"Tell me, how am I different from them?" All are beauties, all can give you children, how am I different?
Ye Zao was doing it on purpose, wanting... to force Fourth Master to realize where the difference lies.
Otherwise, if she only mentions being different now, what if a few years later he meets another 'different' one?
For a moment, Fourth Master couldn't answer.
