Come on, you can't take a bath together and say it's for business. No one's going to buy that.
Yuri shipping, I have to give prop to the writer for fleshing out these two characters rather than making them walking collections of tropes. The mangaka is doing a fine job too, since I almost forgot this is a novel adaptation. Many artist just copy paste dialogues from the source and forget to take advantage of manga's visual cues.
