Severus Snape was your father and it wasn't unknown to anyone that he disliked Harry Potter since the latter's father had bullied him and made his teenage years a misery. You on the other hand, you didn't mind Harry and would sometimes talk to each other. This made Severus annoyed. You were in your father's office completing some homework whilst he graded exam papers. "What's going on between you and Potter?" He asked, not looking up from the pile of papers he was working on.
