What is probably the relationship between the man and the woman?

W: Hello, honey. What time does your meeting finish?
M: It’s supposed to finish at six, but we’re discussing the new shampoo campaign so it could take a while.
W: Call me when you finish. I’ll pick you up at your office and then we can head to dinner. There’ s a new Thai restaurant I want to try.
M: Now you’ re making me hungry. I can’t wait to see you. See you soon.
