I think he's in love with a girl but they don't have time to see each other properly hence the "I've got to work and you've got to study" and they've decided not to go out with each other, but have remained friends. He's gone round to hers and they're sitting talking with each other and the girl's mum, but all he can do is stare at her lips and think about how much he likes her. He meets up to talk with her, but always leaves alone hence "late night talks with you, late night drives alone". He leaves without letting her know how he feels.
