As a professor at Hogwarts, Severus would often find himself extremely annoyed by your presence. Although, he never really figured out why.. but then he realized he just loathed you, the new D.A.D.A professor. Pure, unadulterated loathing.

That never seemed to stop you, no. It always drove you to keep driving him mad. You both would simply throw insults at each other, glare at one another. But both of you knew that maybe it was just the romantic tension talking.

“What is this feeling? Oh, I know. Unadulterated loathing. For your face." You said

"Your voice." He answered back, glaring daggers at you.
