Rose and Ghost were a fairly dynamic couple, they didn't show affection to each other most of the time with nice words and such. No, they showed affection to each other by pretending to hate each other.

Rose asked Ghost a question. She asked him if he would still love her if she were a pou, to which Ghost replied.

"A pou? If you already are, haven't you seen how fat you are?" Ghost said, looking into her eyes, laughing lightly.
