Since when did I become Granger not Mudblood

Hermione's pov

I was sitting on Ron's lap reading a book. We were on the train to Hogwarts to complete our 7th year and I am super excited, I'm going to finally have a normal year at Hogwarts there is no Voldemort or horcruxes to find. Ron's hands were around my waist, we had a great summer together after the chamber of secrets, and I was deep into a 7th year potions book...
"Ukhmm Mudblood" I flinched at that word, who still uses that? None does the war was over I looked up and of course it was Draco. Ron's grip tightened around my waist

"Malfoy" I replied
"McGonagall wants to see us in her compartment"
"And why should we trust you, how do we know this isn't a trick" Ron asked his grip getting tighter
"Because if Mudblood here wants to be head prefect then I suggest she goes now" Draco snarled

"Me I'm head prefect"
"Well obviously your a know it all Mudblood whereas I'm head prefect because of my good looks and talent" he said with a smirk, I laughed then suddenly stopped as Ron's grip got tighter
"You..your head prefect how could you possibly be a head prefect your a Death eater" Ron asked furious
"EX-deatheater, and well I don't know about you mublood but I don't wanna be late so are you coming or not?"
"Her name is Hermione" Ron shouted
"Whatever Weasel"

"Ron lossen your grip and let me go"
"Your not going with him Mione"

"Your not my father Ronald, let me go" I pulled away from his grip and followed Draco out who had a huge smirk on his face.

"He's over protective" Draco said as we walked down the train, we were at the back so we need to go threw alot of carriges to reach the front

"Who is?" I questioned
"Your boyfriend"

"Well could you blame him, your a Ex-deatheater" he smiled at me and carried on
"Well tell your boyfriend I've changed" He said as he let the door smash in front of my face I opened it and jogged up to catch up with him laughing

"You really think you've changed when your here calling me Mudblood and slamming doors in my face"
"We're here" He opened the door to McGonagall's carriage and sat on the sofa, I hesitated but sat next to him keeping my distance
"So Miss Granger, Mr.Malfoy you are this years head prefects you will both be responsible for head prefect duties such as patrolling the halls at night, organising balls and hogsmeade trips however to thank you, you both will share a private common room and have the password to the prefects bathroom"
"I have to share a common room with that Mudblood" Draco shouted pointing at me
"Now, Mr.Malfoy language, you have this opportunity as a second chance, not everyone gets one so I suggest you don't waste yours. Now you two go and collect your trunks, you both will be staying in heads compartment until we get to Hogwarts where you'll both help the first years safely to Hagrid"

"Thank you professor" I said and walked back to my compartment.

I reached above Harry and Ginny hoping they wouldn't ask any questions
"Where are you going" Harry, Ron and Ginny asked at the same time

"Heads compartment of course"
"With ferret" Ron asked worridly

"Yes with Malfoy, he is head prefect I will also be late to dinner we have to make sure 1st years get to Hagrid safely Bye" I kissed Ron on the cheek and quickly walked out the door so they couldn't ask more questions and headed towards the compartment.

Draco was already in there, I tried to lift my trunk to get into the space above our heads but it was too heavy with all the books and clothes

"Are you not going to help me" I asked Draco, he opened one eye and shut it again
"Why would I help a Mudblood"
