You are a new professor at Hogwarts. You took Professor McGonagalls' place because she had to do something for the year. You are the transfiguration teacher. The other teachers are Professor Snape (He likes you), Professor Lupin (He secretly likes you and you secretly like him back), and Professor Flitwick (Good friend)

Right now, you are in your office, grading papers late at night, until someone knocked on your door
