Pretty self-explanitory really, he met this girl, love at first sight, but she's playing the longest game of hard to get in the history of dating. He wants to show her he'll wait as long as it takes until she finally cracks and agrees to go for a coffee at nero's. Out of context this might be a bit stalker-esque however bob's lyrics paint the picture of a hopeless romantic and not fortunatly, a derranged stalker.
