Draco Malfoy and Hermione Granger somehow managed to act cordially when they had to room together in the eighth year dormitory at Hogwarts. So when a paperwork mix-up means they'll have to do the same at Oxford University, Hermione assumes it won't be so bad. After all, she's broken things off with Ron, and she and Draco had been friendly that last year at Hogwarts... Sometimes even close to more than friendly.
But something is off here at Oxford with this wizard, and she can't quite put her finger on it.
She's definitely learned one important lesson at university: everyone should give a fuck about an Oxford comma.
