Boy invites Girl over to his place. He drives her there. He drinks too much and so cannot drive her home until morning. He instructs her that he will get her home in time for her to get ready for work and be on time. Girl is hesitant, but in light of the alcohol, understands the reasoning.
Conveniently his bed is the best place to sleep. He insists the set up is honorable.
