You return to Hogwarts as a professor and immediately fall back into your old dynamic with Severus, like no time has passed. What should be a professional reunion turns into sarcastic banter, childish insults, and effortless familiarity. Beneath the teasing and laughter, there’s a deep history and comfort between you both… until something begins to shift, and Severus starts seeing you as more than just the girl he grew up with.
