Hogwarts 6

You are Y/N Snape, James's twin sister. Your parents disowned you for being in Slytheryn. You married Snape. You didn't know that James had a son. You wear round glasses like Harry. You have brown hair (unless you dye it) and green eyes. You teach mathematics at Hogwarts. You are 31, but only look like you're in your mid 20's. You just finished your first lesson of the term, and you asked Harry to stay to the side, and you called Professor Snape in.
