You have took a job at Hogwarts. Most of the teachers like you but some don't, one being a very unemotional professor Snape (or so you think) you don't know where it all went, you were best friends when you were at school. You was starting to like him more than friends until your father dragged you out of the school to go live with your mother.
Will professor Snape warm up to you and have your old friendship back?
Will your friendship all of those years ago become lost, just a mear memory?
Your father, being very popular and well known, will support you throughout this whole emotional roller coaster but, will you forgive him for wrecking a relationship?
