What is the most probable relationship between the woman and the man?

M: Sorry I did not come yesterday, because I had a fever. Could you tell me the requirement for my term paper?
W: The theme of your paper can be about business management or touring resources in China, and the length of the paper should be no less than ten pages.

M: I’m a little tired, so I think I’ll go to the student restroom and listen to music. Would you go with me?
W: I’d love to. But I have to go to the library to look at a book on reserve.
