What is the possible relationship between these two speakers?

M: Hi, Lucy.
W: Hi, Frank.
M: What’s wrong with you? You don’t look so well.
W: Yes, I have bad news.
M: What’s it?
W: I failed the maths examination.
M: What? That’s unbelievable. I remember you are very good at maths.
W: But these days I have spent too much time watching TV and playing computer games.
M: Oh, that’s too bad. I’m sorry to hear that. But don’t worry too much. You can catch up with others next time if you spend more time studying maths. I’m sure of that.
W: Thank you very much. I’ll try my best
